I scoured the Internet again without a lot of success.  There is csync
but it seems young and does not seem to use rsync like differentials.
Thee is git-sync but it is a command line script and setting up a
complete git repository seems a little overkill for our user needs.

Persy looked rather interesting although it also uses git.  However, the
directories need to be empty when one first synchronizes.  Again, great
for developers synching branches but not really end user friendly.

It looks like drsync (http://hacks.dlux.hu/drsync/) is what we'd want
but it is still a command line tool.  Does anyone know of a GUI front
end to drsync? Thanks - John
