BitTorrent 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 a Torrent is one of the most efficient way to share a file with a large audience, without
the need of a huge bandwidth connection.
