I looked at that, and I'd like to post two wishes:
 * Please provide representations with a SHA1 (or similar) field;
   then it's possible to split blocks on manber-borders, to save
   space.
 * Furthermore, how about allowing the plain data to reside in files?
   Would make the database much smaller, and then these data blocks
   could possibly be shared among multiple repositories.
   (Really easy, too, if they're named by their SHA1, for example).
   That should allow for zero-copy IO, too (at least for sending data).

Regards,

Phil
