I think that "distributed copies" measures how many complete copies of the file you could get if you took all the pieces that everyone has and assembled them. For example, consider a five-part file. Alice has: 1 2 3 4 Bob has: 3 4 5 Carol has: 1 2 4 You could make one complete copy of the file from all this, so there'd be 1 distributed copy. If Carol got piece 5 from Bob, then you could assemble two complete copies. That's the integer part of distributed copies; I'm not sure where the fractional part comes from. Maybe it's the size of the largest distributed incomplete subfile divided by size of file, but that's just a shot in the dark. > Does the tracker ever inject packets into the torrent when needed (like > when seeds == 0 and distributed copies < 1.0)? No. The tracker doesn't have a local copy of the file. If there are no seeds and < 1 distributed copy, everyone's download will stall before finishing -- Samuel Merritt OpenPGP key is at http://meat.andcheese.org/~spam/spam_at_andcheese_dot_org.asc Information about PGP can be found at http://www.mindspring.com/~aegreene/pgp/
