Remote file syncronization

I'm trying to find a way to syncronize files across an insecure network automatically. Tsync looks good, unison rocks, and there are some more hardcore setups like drdb.

Can't seem to find a setup for tsync on debian, and unison requires an administrator to accept changes (which is good). I've even thought of sshfs, but I'm wary about its stability and the safety of the files involved.

My new plan:
Setup drone account with unencrypted dsa psk, and rsync over ssh. I think this will do it.
