I don't use P2P networks anymore due to all the Malware that you can get off them not to mention the illegal act of using them! I haven't used P2P for over 12 months but I am just curious as to the legal position of my ISP (AOL) as even though it is an American company would they be legally bound to UK law as mentioned in my link?
Its a shame that P2P and file sharing has attracted so much negative publicity because of the illegal side of it.
The other side of the coin, its a very important tool. Without programs like Bittorrent you would not be able to download a lot of the open source software, like operating systems, which are large file downloads. These would not be free if the software house had to supply the bandwidth for such large downloads.
