-u will make sure that newer overwrites older, not vice
versa (warning- make sure clocks are right!- I don't do this
till I'm sure ntpd is running on the machines).

and by source-address and destination-address you of course
mean path-to-file-or-directory in this context (though of
course one of the other can also be prefixed user@host:
which implies ssh transport).

rsync won't sync deletions though- unison's probably better
if you want that.
