You can find it on GMane, too:
  http://thread.gmane.org/gmane.comp.version-control.git.gittorrent/1

It would be nice if it was send to git mailing list too, perhaps directing replies to gittorrent mailing list only by default.

A short summary of this thread (please correct me if I am wrong):

 * Tracker: representing "metainfo" files, working tracker (test)
   is in progress

 * Core infrastructure: "Commit Reel" sorting algorithm implemented[1]
   B-tree index for fast querying.

   To be done is determining minimal set of edge objects which define
   reel (that can be passed to "git rev-list --objects-edge" to get thin
   pack representing reel).

 * Peer to Peer: handshake and two trivial messages[2] implemented.
   To be done are (minimally) "References", "Blocks", "Request" and
   "Play" messages.

Footnotes: ========== [*1*] "the current implementation is quite slow (requiring two calls to 'git-cat-file' for each object)" <-- why you don't use '--batch' or '--batch-check' options to git cat file: see also Git::Repo and friends implementation send by Lea Wiemann to git mailing list as part of "Gitweb caching" project? BTW. by keeping discussion off the list, you are off the knowledge of git community, too.

[*2*] _What_ are those "two trivial messages"?
