Didn the courts just rule that peer-to-peer networks are perfectly legal?
In the Grokster case, a district court did rule that the Grokster and StreamCast networks couldn’t necessarily be held liable for the illegal activities of their users. That ruling is now being considered by a Court of Appeals. In any case, the court also made it abundantly clear that whether or not a network itself can be held responsible, the users of that network can clearly be guilty of copyright infringement.
