The Age looks at file sharing and KaZaA, in an article called Singing in cyberspace. Beyond the issue of a US Court trying to control activities beyond its borders, it also raises this question:
The legal issues go far beyond music. A key question is whether there is liability in making it possible to infringe a law. That's a minefield. A decision along those lines might render car makers responsible for speeding fines or video camera companies liable to prosecution for child pornography.I don't believe that the recording industry in America will agree with that perspective. But, it may be a view that they have to entertain and consider as they readjust their business models for a future where online sharing of music happens.
