Yes! rsync is one of the star examples of excellent OSS. I think it was 
written by the same guy who did samba.

I use rsync for updating our web site - which often has new versions of 
binary software in it. Even running it over ssh it is very fast.

To give you an example, I changed the email address on 100+ pages of the 
web site (to avoid some of the virus bounce messages) yesterday. It took 
only about 20 seconds to rsync the remote site. moving whole files would 
have taken several minutes.

You could try making the tarball on the other end and rsyncing the 
resulting file - always keeping it the same name on both end - Depending 
on how well it calculates the changed data that might work pretty well.
