   Hmm... I'll be the first to admit that I do not exactly know what
rsync is. But if I remember correctly, unison uses "the rsync
algorithm". I guess my next question is: Is it the rsync algorithm that
requires vast amounts of RAM, or is it merely the implementation of it
in unison?

   Perhaps I will give rsync a try and see what happens.
