Hi!
If I have a bittorrent tracker package, like the appended, it would be
cool to have a feature to find out what torrent it is (e.g. torrent file
name). Of course, with the info_hash being a hash, this is not so easy.
At [0] you can find a reverse info_hash database I made from 12000 of
the most popular torrents from The Pirate Bay. A lot (if not most) of
the torrent tracker traffic should be distinguishable, and it is not
that big (1.3M).
Also, a howto is linked there for making such a database.
Tell me what you think,
Johannes

PS: The utilities I used are not optimized for calculation speed
