I'm all for userland solutions, especially ones that can work from a directory
base instead of a partition level. As long as they do the job and do it
efficiently. I will give Unison a go and compare it to rsync, at least.

The problem I have with the rsync/unison solution is that, even if unison has
a file list already, to check for updates, it still has to scan every file,
does it not? Otherwise, how does it know that a file is different from what
is in its db of file statuses?
