Looking at the spec <http://www.bittorrent.com/protocol.html>, I see a 
filename (or list of filename/length pairs), tracker URL, and a set of 
fragment checksums. Most of the size would be the checksums. How do you 
propose shrinking this to fit in a URL? I suppose you could designate 
trusted peers (eg. initial seeds) to host the checksums.

My point was just that bencoding is a Python-centric structure dump. 
Data::Dumper is the Perl equivalent, and PHP also has a structure dump.
