One option you can try is a custom fam client which "watches"
directories for change and then uses rsync to update the remote server.
I had started on a python app to do just that, but because of the large
number of files I needed to monitor, found that fam wasn't up to the
task, if your needs are smallish - only a couple thousand files, then
something like that might work for you, you can also try using the
dnotify package and a simple bash script.
The real holy grail sort of solution is a combination of drbd and
opengfs, unfortunately integration of those two systems, while planned,
is not yet implemented. If a failover sort of setup will work for you,
you can use drbd with heartbeat to give you automated failover and
