Well, Iv finally broken my protocols forum cherry,
BiTorrent, the new latest and greatest transfer protocol.
BitTorrent is a Peer-to-Peer Filesharing program created by Bram Cohen. It is a protocol for distributing files. It identifies content by url and is designed to integrate seamlessly with the web. Its advantage over plain http is that when multiple downloads of the same file happen concurrently, the downloaders upload to each other, making it possible for the file source to support very large numbers of downloaders with only a modest increase in its load.
Using this new protocol, it becomes possible to transfer files to hundreds of people using relatively little bandwidth by any single individual.
Bitorrent works on Windows, Macs, and Linux
