Altough it seems a reasonable, positive, even obvious law, it might also be the first step to make it easier to sue people from sharing. If some dumb user does unawarely install something in his/her machine, not bothering to read some comprehensive, law-enforced EULA, and share some DMCA-protected content without knowing, seems to me that RIAA lawyers will have a much stronger case against them - that might be the motive they are being specific about P2P programs, and not every junk people put on their machines. IANAL, but it seems to me that "I didn't know these files were being shared" kind of defenses will hold much less under these new provisions, and it's possible this might be the hidden objective of this law. I hope some lawyer here in /., proves me wrong on this.
