Memo to would-be Silicon Valley moguls: do not double-cross a pair of highly litigious billionaires.

After weeks of back-and-forth legal jousting, the tech heavyweights fighting over Skype are set to announce a deal in which the founders of the popular Web-calling service would regain a stake in the company they sold to eBay (NASDAQ: EBAY) in 2005 for $2.6 billion, according to Bloomberg. Nice trick.

The pact ends an at-times vicious soap opera replete with accusations of back-stabbing, dishonesty, and outright theft against Mike Volpi, the pair's one-time Golden Boy, who they believe double-crossed them. The legal circus held up eBay's proposed $2 billion sale of Skype to a consortium of private investors led by Silver Lake Partners and Andreessen Horowitz, the investment firm of Marc Andreessen, the billionaire co-founder of Netscape.

The question that I haven't seen answered in any of the articles relating to the partial acquisition of Skype from eBay (NASDAQ: EBAY) by a team of private investors is, who will own the underlying IP that runs the Skype P2P communications network?

That question must somehow have been answered if savvy investors such as Silver Lake Partners and Netscape founder Marc Andreesen's investment fund, felt comfortable forking over $1.9 billion to eBay.

And as TechCrunch's Mike Arrington points out, eBay did okay on this deal, emerging with a paper gain and still some share of any potential upside.

eBay Inc. (NASDAQ: EBAY) announced Tuesday that it has reached an agreement to sell most of its stake in Skype in a deal that values the online telecommunications service at $2.75 billion. eBay will get $1.9 billion in cash and a $125 million note from the buyer.

An investment group led by the private-equity firm Silver Lake, including Index Ventures, Andreessen Horowitz, and the Canada Pension Plan Investment Board, will buy the 65% stake in the company. eBay, which will retain a 35% stake, expects the deal to close in the fourth quarter of this year.

While eBay (NASDAQ: EBAY) said earlier this year that it was planning to spin off Skype in an initial public offering in 2010, it is now being reported that eBay is looking for a buyer willing to pay $2 billion or more for the internet telephone service provider.

Those interested in a buyout may include Andreesen Horowitz and Index Ventures, which were early investors in Skype before its eBay acquisition in 2005. A group of well-known venture capital and large private equity firms are pooling resources to join the bid, according to a source close to the deal.

Though tech M&A has been fairly quiet of late because of macro-economic conditions, the rumor mill is churning strong, with Google Inc. (NASDAQ: GOOG) in the middle of two rumored deals.

Shares of online travel site Expedia Inc. (NASDAQ: EXPE) were up more than 2% Wednesday on top of Tuesday's 10% gain on rumors of a potential buyout by Google. Meanwhile, TechCrunch is reviving a rumor from last year that eBay Inc. (NASDAQ: EBAY) is in talks to either sell Skype to Google or the two sides would form a partnership involving the Internet phone service provider.

When we last wrote about a possible Google buy of Skype in November, we didn't think anything was imminent. After all, eBay would have been selling at a low point, having just announced the unit was underperforming. At that time, Skype's quarterly revenues were $98 million. In its last earnings report, Skype's revenues were reported at $115 million, a 76% increase versus the prior year and a 17% increase quarter-over-quarter. So it's not like Skype is a total disaster.
