I looked at the syncdat feature list (
http://www.dataexpedition.com/syncdat/features.html ).  Aside from the
claim of much better performance, syncdat appears to be equivalent to
a combination of rsync, unison, and ssh.  Mike, am I missing something
that syncdat can do but rsync and unison can't?  And is more
information available about the benchmark that found that syncdat is
"Up to ten times faster than rsync" (
http://www.dataexpedition.com/syncdat/ )?
