BT is actually the worst case scenario for large, low-interest files
(but it's perfect for large, high-interest files).
By way of comparison, a certain production house leaked a copy of the
pilot for a TV show because it had been canceled and they wanted to try
to drum up some grass-roots support. It didn't work, and the show never
saw the air.
A year later, I tried to pull down the torrent. After a day of waiting
for the download, I fired up gtk-gnutella. The search took an hour to
find the file, and the download finished before the torrent by about 12
hours. The torrent was mostly idle, waiting for a client who had the
missing bits of the file.
This has been my fairly repeatable result with old operating system
versions, strange platform ISOs, folk music that's been released, and so
My theory as to why is that bittorrent has a small chunk size and
randomizes access. Gnutella has a larger chunk size and while it
randomizes the first chunk from each available swarm source, it then
continues linearly through the file as long as the next chunk is not
already downloaded or being fetched from elsewhere; it then applies a
heuristic that I haven't fully looked into (and may be client-specific),
but the net result is that I almost never find a file on a Gnutella
network for which less than 100% of the original file is available.

If you do so, it doesn't hurt to provide the same service for gnutella.
There's a server-only called quack out there that serves roughly the
same purpose as a tracker.
It's not in extras right now, but it could be with minimal effort.
