sounds promising.  but:

1: its done from 'inside' the VM, so it might allow better network
backup systems but not replace them.

2: it does nothing about complex applications with their own caches
and file structures: IOW, databases.  if you get an 'in VM' snapshot
capability, you still have to flush caches and suspend operations for
the snapshot.
