Bittorrent doesn’t use multicast.<br class="">

mechanism - it's not an infrastructure for maintaining
or mirroring files. It's essentially another, sometimes
more efficient, option for click-to-download (e.g., ftp,
http, bittorrent). And it's only more efficient if
multiple people are downloading at the same time.</p><p class="">Miles<br class="">

No, Bittorrent uses DHTs and accesses as many copies of
a given file as users choose to share. It has to be
running to serve files, however.

Hi again. Please look at Bittorrent and
tell us how it is different<br class="">

Bittorrent has the advantage of already

widely used for sharing linux distributions

Bit torrent is transient. It's more like an
ad-hoc multi-cast <br class="">
streaming. When nobody is downloading, there
may be only one copy of <br class="">
the file.<br class="">
<br class="">
Now gnutella, and some of the other P2P file
sharing systems - that <br class="">
replicate copies, or distribute files across a
distributed hash table - <br class="">
that's another story entirely.<br class="">
