Hash: SHA1

It's technically mike's side that handles torrent generation currently,
not ooodev.org.

If you have an rsync folder that I can use to automatically load the
.torrent files from your side, it can be set up fairly trivially to have
the torrents authenticated on the depthstrike.com trackers within 2
hours of generation automatically.

It is currently not a good idea to accept all torrent infohashes without
discrimination, especially for this project. The load spikes are
potentially system crippling.
