is it true that copyright holders can use bitTorrent somehow to get the IP addresses of folks who are uploading files? or maybe they can get the IP addresses of folks who are downloading files? I don't use bittorrent or any P2P software, so I dunno how they work. I just read in the papers about how college students are getting letters demanding that they pay the copyright holders or face court action, so they may be able to get their info without the formality of a subpoena.
