Yep.  Encrypt a file with 'gpg -c'.  Encrypt it again with 'gpg -c' 
using the same pass phrase.  You'll get a completely different file.

I just started experimenting with client-side EncFS and running rsync or 
unison on the underlying native file system.  Similar goal, different 
approach.  Sync underneath EncFS compares encrypted file to encrypted 
file so it doesn't have the encrypt everything overhead that rsyncrypto 
incurs, but it leaks file metadata like a sieve leaks water.
