rsync itself does all of that, and it's pretty efficient at it. Oh - I
see, your optimisation is to declare a hash of the top-level directory
and exchange that first, and only recurse if they differ (like git
does).

Hmmm. Wouldn't that be a good enhancement to rsync itself? Perhaps
there are a few such patches to rsync in existence already...?
