P2P is legal, and torrent is legal too. What is illegal is the sharing of copyright-protected media, no matter in which medium is being shared. It's not the P2P paradigm which is illegal. Although maybe I misunderstood your post and missed the point by far
Every time that companies, governments, stupid people in general tries to act "against P2P technology" make me want to put the world to the fire. They don't/can't understand that P2P has legals uses and for some kind of distribution schemes it is very important!
Sorry for going into OT territory
