I actually used this for a prototype system to allow push over git://
with secure authentication via PGP; basically it used an update hook
that disallowed any ref change that wasn't a signed tag, and then in the
post-update hook, moved the tag to an audit log refspace and put the
referant commit in the refs/heads/* location.

The hooks (probably racy etc) can be seen under
