Looking at the Tracker GET request in the protocol spec at 
<http://www.bittorrent.com/protocol.html>, I don't see how the info_hash 
provides any integrity. I understand how the fragment hashes do that, but 
those are computed from the payload file, not the metadata file, and aren't 
sensitive to the representation of the metadata.

I also don't see any mechanism for preventing spoofing of one's statistics 
to the tracker.
