Actually, torrenting starts to get interesting with swarms.  The more
people that seed, the greater the chances that the packets you need
will be immediately available.  Even if they don't have a lot of
bandwidth as individuals, as a collection they're as accessible as a
high-speed disk drive.

Mine's 768K, and that's the low end for my ISP.  I typically set aside
150K for bittorrent upload and don't feel it with anything else that I
do.  I know that's not a huge contribution, but again, swarms.

Set up a torrent for AOO and I'll be happy to help seed.  And I
promise to not block Argentinians.

Dude...Are you citing yourself?
