It worries me because P2P is a powerful censorship prevention mechanism. Requiring a license to use P2P technologies would mean disallowing much more than just torrents by default. Not only that but lots of illegal content distribution takes place on standard HTTP servers which would presumably not be considered P2P. With that said, disallowing any protocol which is currently allowed today seems like it would open the door for large corporate and governmental interests to disassemble what we know as the open internet. Furthermore it sounds like it would be complicated to deal with ownership of derivative work and resolution of disputes.
