Ok, this may be a strange question, but let's start:

If I illegally download a movie (for example...) from a HTTP Web Server, there are many routers between me and the Web Server which are forwarding the data to my PC. As I understand, the owners of the routers are not legally responsible for the data they forward (please correct if I'm wrong).

What if I would install a client of a peer-to-peer network on my PC and this client (peer) would forward copyrighted content received from peers to other peers?

Hope someone understand what I mean ;-) Any answer or comment would be highly appreciated.

Update 1: I'm asking this question because I want to develop a p2p-application and try to figure out how to prevent illegal content sharing/distribution (if forwarding content is really illegal...)

Update 2: What if the data forwarded by my peer is encrypted, so I'm technically not able to read and check it?
