Joost, the video-on-demand program created by the founders of Skype and Kazaa, has been named as a defendant in a lawsuit filed a year ago over the technology upon which Skype and Joost are based. StreamCast Networks owns the technology underlying Internet-calling provider Skype's software. In its lawsuit, StreamCast claims that Skype founders Janus Friis and Niklas Zenstromm breached contract by improperly transferring technology rights away from StreamCast. StreamCast, which created the Morpheus file-swapping software, added eBay as a defendant to the lawsuit a year ago. eBay bought Skype in 2005. Joost was launched commercially May 1.
