pointer to BattleTorrent which promises to be easy to set up for novice users.
I have little interest in MP3 trading as either I or my company paid money for them (think classes not songs) but I do have interest in those updates (Mandrake for one) which become available via BT before anything else. Also, I'd rather archive data (news and articles) rather than eating up storage space on 4 year old drives with MP3's I'll rarely listen to. Thus my novice P2P experience.
Anyways, I hope that there's an easy-to-use BT flavor available the next time I want the new *nix distro.
