Sorry, missed the original message.  Anyway, the big difference between
rdist and rsync is the incredibly cunning synchronisation algorithm used by
rsync.  Essentially, it just sends diffs, when it can, rather than whole
files, and pipelines transfers so it works efficiently even on high-latency
links.  As far as I know, rdist always sends whole files.

IMHO, if you have a choice, use rsync.
