Microsoft–furious over a recent talent grab of its top advertising exec by Facebook–has been considering a wide range of options, including legal action to block the move, according to sources close to the situation.

Lawyer at both companies have been in back-and-forth talks in recent days after the hiring of Microsoft’s global ad sales head Carolyn Everson by the Silicon Valley social networking powerhouse to be its VP of global sales.

Among the more likely solutions being discussed: Barring Everson–a longtime ad sales exec who came to Microsoft from MTV Networks–from using any strategic information she learned at the company and also from contacting certain ad clients on behalf of Facebook for a certain period of time.

While a legal action to stop her from actually taking the position is the most serious option, it is certainly not without precedent for Microsoft. The company recently got a temporary restraining order to block one of its top government relations execs, Matt Miszewski, from working at Salesforce.com, pointing to non-compete and confidentiality contracts.

Whatever happens, it is clear the Everson hiring has infuriated Microsoft execs, especially CEO Steve Ballmer, since the company regards Facebook as a close partner. Microsoft is also a longtime investor in Facebook.

While considering a temporary restraining order against Everson in this kind of situation–since it is essentially the same job–is standard operating procedure for any company, several sources said tensions are higher than usual.

“This is just tone deaf on Facebook’s part not to think this would not be a problem,” said one person.

One particularly irksome aspect–top Facebook execs did not call Ballmer before news of the appointment leaked out to assuage the situation.

Facebook COO Sheryl Sandberg did release a statement when BoomTown broke news of the move in mid-February, in an attempt to make nice.

“Microsoft was one of our earliest partners and is still one of our most valued,” she said, in part. “We look forward to continuing to expand our relationship with them.”

Her dulcet words have apparently not worked.

In fact, the talent raid came as a surprise to many at Microsoft, especially since Everson (pictured here) had been hired in June after a long search and had become a high-profile presence at internal and external Microsoft events.

That included organizing the splashy “Imagine 2011, Microsoft Advertising’s Marketing Leadership Summit.” The event is set to take place at the end of March at the software giant’s Redmond, Wa. HQ and will include an evening concert by the band Train.

Now she will be doing such things for Facebook, where Everson will be replacing longtime and well-regarded ad exec Mike Murphy, who left the Palo Alto, Calif., company last fall. She will report to former Googler David Fischer, VP of Advertising and Global Operations.

Having a top exec who is amenable to and well known by Madison Avenue is key for Facebook as it ramps up its business, in anticipation of an IPO next year.

Despite being private, Facebook has recently been valued at between $50 and $60 billion by investors, who have been eagerly buying up shares of the company on secondary markets.

Under Murphy and Fischer, ad sales have been doing well already. Facebook’s share of online display advertising has more than quadrupled, from about three percent to almost 14 percent of the nearly $9 billion U.S. market, according to a recent survey.

In growing so quickly, Facebook has grabbed ad revenue–reportedly $2 billion last year–from old online powerhouses, especially Yahoo, Microsoft and AOL, and is also in a big fight with Google over premium ad sales.

Facebook’s surging usage and engagement are the reasons for the increased interest from advertisers, as well as its global growth in both market share and mindshare of consumers.

The opportunity at Facebook is clearly a big–and probably irresistible–move for the dynamic Everson, who has mostly worked in the mainstream media for much of her career.

Still, while movement of execs among top tech companies is not uncommon, there has been a lot less from Microsoft to Facebook.

Instead, Facebook has been most aggressive in its efforts to attract talent from Google.

No longer. In fact, the week before Facebook grabbed Everson, it also hired an up-and-coming exec, Chris Daniels, GM of Bing Mobile Product Management, to be its director of business development.

Still, there is some hiring war history between the companies. In late 2008, Microsoft’s Ballmer managed to lure former Yahoo exec Qi Lu to run its Online Services Division, several sources at both companies said, after he had told Facebook he would work there as its engineering lead. Lu had also been heavily recruited by Google.

Eventually, that was water under the bridge, which is what Facebook is hoping will happen with Microsoft over Everson.

Also important in the weighing of options at Microsoft is the obvious importance of keeping up good relations with Facebook. It is an important partnership, especially for its Bing search business, as an advantage over Google.

“Everyone is hoping to resolve this amicably,” said one person close to the situation. “There has been some damage to the relationship for sure, but the question is whether Microsoft wants to do something that would escalate that damage.”

Not surprisingly, both Facebook and Microsoft declined to comment on the fracas.

“AT&T did not file this lawsuit because Verizon’s ‘There’s A Map For That advertisements are untrue; AT&T sued because Verizon’s ads are true and the truth hurts.”

– Excerpt from Verizon’s response to AT&T’s complaints about its new ad campaign

Verizon was right. The truth does hurt. And it is especially painful when it’s meted out by a court of law. A U.S. District judge on Wednesday denied AT&T’s request to force Verizon to pull its “There’s A Map For That” and “Island of Misfit Toys” commercials, saying that while the ads might be “sneaky,” they are not deceptive.

“People might misunderstand [Verizon’s commercials],” said U.S. District Judge Timothy Batten, “but that doesn’t mean they’re misleading.”

He gave AT&T (T) another chance to make its case at a Dec. 16 hearing, but given his dim initial view of the company’s complaint, the carrier seems unlikely to prevail.

AT&T plans to press on with the case anyway. “While we are disappointed with the court’s decision on our request for a temporary restraining order, we still feel strongly that Verizon’s ads mislead consumers into thinking that AT&T doesn’t offer wireless service in large portions of the country, which is clearly not the case,” AT&T spokesman Mark Siegel said in an email. “We look forward to presenting our case to the court in the near future.”

In the meantime, AT&T has begun running some attack ads of its own. Sadly, the first effort is not nearly so clever as Verizon’s (VZ) and features far too much Luke Wilson and far too little humor.

A Los Angeles federal judge has issued a preliminary injunction against BlueBeat, a California-based site that had briefly sold the band’s music, arguing it used “psycho-acoustic simulation”–basically, making a note-for-note recording of the band’s recordings–to make the songs its own.

The same judge had already issued a temporary restraining order on behalf of music label EMI Music Group against the site earlier in the month and had scheduled a hearing for Friday, Nov. 20. But this ruling cancels out the hearing and by any reasonable standard should end the case.

Then again, this whole story has been a head-scratcher from the start, so who knows? Maybe the BlueBeat guys will try an even more preposterous argument down the road.

Part of me thinks that the whole thing may be some sort of Negativeland/U2 hack/stunt/performance art piece. Or maybe there were a lot of mood-altering substances involved. Or maybe it’s part of a conspiracy to create work for copyright lawyers.

Whatever. I’ve embedded the court ruling below, if you insist on reading it. But here’s a clip of Richard Pryor reading the alphabet on “Sesame Street,” which is just as edifying and much more entertaining.

Marked by panic selling and wet-your-pants fear, it was one of the worst weeks in the financial world’s history–a week that cut the legs out from under Google (GOOG), beat Yahoo until its market cap bled purple and caused the Dow Jones Industrial Average to swing more than one thousand points on an intra-day basis.

It was a week that saw Sequoia Capital warn its portfolio companies to prepare for a protracted downturn or, in the words of partner Michael Moritz, be “spattered on windshields and radiator grills and be forgotten.” Turns out Bubble 2.0 sounds a lot like Bubble 1.0 when it pops.

Beneath the screams of agony echoing across Wall Street, there was other news worth noting:

• Advanced Micro Devices (AMD) announced plans to spin off its manufacturing operations.
• “Legal” turned out to be a poor choice of adjectives for RealNetworks’ RealDVD (RNWK), the company’s new “legal” DVD ripper. A judge extended the temporary restraining order barring the company from distributing it.
• This just in: Time Warner’s (TWX) AOL and Yahoo (YHOO) are still talking about a merger and Generalissimo Francisco Franco is still dead.
  Where is Microsoft (MSFT) in all this? Sitting on the sidelines hoping the deal will go through.
• Finally, activist investor Eric Jackson, the creator of the Yahoo! Plan B investor community, revealed Yahoo! Plan C: his hedge fund’s divestiture of its Yahoo stake.

“I am extending the temporary restraining order because I’m not satisfied in the fact that this technology is not in violation,” Patel explained. “There are serious questions about copyright violations. There are questions about violations of the (Digital Millennium Copyright Act), and violations of these companies’ agreement.”
