Grokster loses

This is slightly outside of our jurisdiction as a gadget site, but screw it, this news is too big: Grokster just lost. By a unanimous vote the Supreme Court held that software developers are violating federal when they create file sharing applications and then also take "affirmative steps to foster infringement." It's hard to conceive of all the wide-ranging implications of this ruling. Sure it'll mean that the record labels and movie studios can sue the heck out of P2P companies that facilitate unauthorized file swapping, but the real question is, what consititutes an "affirmative step to foster infringment"? Seems vague enough to apply to all sorts of stuff, and no doubt the RIAA and MPAA are uncorking the Cris right now.
