I'm doing a report for a school newspaper about the reliability and safety of free p2p networks..would anyone want to pitch in a few words about the following programs? Would greatly appreciate the time saved with taking opinions.

Programs: Kazaa lite, lime wire, Bit torrent, gnutella (is gnutella and limewire the same application?) and edonkey. If you have any other major p2p network names that I missed, please put those in too. Thanks for the support.
