I've been using the torrent protocol for a few years since I abandoned Gnutella and I've been very pleased.
It's a peer to peer sharing but uses a different protocol. There are many different software packages that you can download for free.
When I asked about the Torrent stuff a couple years back, I got a nice Torrent 101 e-mail from a couple of the regulars here that walked me through the in's and outs.
I'll try to find it and forward it to you if you send your current e-mail addy to
stogiemac at that yahoo place.
