the system-update case is the one I'm looking at. 
or simply a case where a file identical on many machines gets touch()'ed and
the timestamp changed. 

one of the big advantages of replication, is that you don't have to allow an
outside machine to access *all* of the hosts you're trying to back up. Only
need to pass access in to the backup server, which is much simpler.
