You make me laugh. :-) Yes, I guess I've been repeating myself a
bit, heh.

The latest point I'm making is that *even* if you have just one
project per repository, you still have multiple copies of the code in
different directories -- due to the way branches and tags work. So a
single revision number *still* isn't enough to identify the "state"
of a project.
