git-daemon is for the anonymous access case, either started from inetd (or any other external "listen to port, exec service" thing), or with the built-in listening stuff.

It uses exactly the same protocol and logic as the regular ssh clone-pack thing, except it doesn't authenticate the remote end: it only checks that the local end is accepting anonymous pulls by checking whether there is a "git-daemon-export-ok" file in the git directory.

In my tests, the git daemon was noticeably faster than ssh, if only because the authentication actually tends to be a big part of the overhead in small pulls.
