That's a good idea - In my case rsync is super fast, 1-2 min tops, so I 
can afford the lock for that time. But I surely should check more about 
snapshots.

Yes. It is a work of beauty that thing :) I remember how cool it was to 
see mail being replicated when both servers are up and one responding 
for mail when one of the servers is down.
