Red Herring has an article on the Skype-Kazaa deal. It notes:

[T]he two companies are far from strangers. Skype's current CEO Niklas Zennstrom co-created Kazaa before licensing the technology to Sharman Networks in Australia after a flood of lawsuits by the recording and movie industries.

Skype is headquartered in Luxembourg, and is funded by Tim Draper, Draper Fisher Jurvetson ePlanet, Index Ventures, Bessemer Venture Partners and Mangrove Capital Partners. Sharman Networks is based in Vanuatu, and reveals nothing about its backing. Rumors about predatory multi-billionaires abound.
