A Romanian programmer is suing Kazaa, claiming that he wrote the source code for its popular but infamous file-sharing software. Fabian Toader says he wrote the Kazaa software in 2000 while working as a freelancer for the company in Romania. Because he never signed a contract with the company, under US and Romanian copyright laws, he is the legal owner of the software. Toader is seeking $25 million in compensation. For its part, Kazaa notes that this lawsuit is just Toader's latest attempt at "shaking down" the company, so apparently he's made this claim before.
