Good point. This would probably be the easier solution (though this
whole 'svnadmin dump' stuff using a post-commit hook feels more like a
hack, not like a feature).

I can't see why you would need a cluster FS to do this. The main
difference between a network FS (NFS,CIFS etc.) and a cluster FS is the
fact that a cluster FS doesn't use a central server to manage data
access/locking. I think both solutions should work equally well
(although performance most likely is quite different).
