Those of you in the USA (and elsewhere) who are providing networking services or connectivity to others should be aware of possible liability under the DMCA (Digital Millenium Copyright Act) and similar laws in other countries should one of the people you are providing service to misbehave and commit a copyright violation, such as posting copyrighted material on your or their own server, or operating a peer-to-peer (BitTorrent, etc) node that is distributing copyrighted material. It could be expensive.
I recommend you read up on this. A place to start is the Wikipedia article on the OCILLA (Online Copyright Infringement Liability Limitation Act).
