Have you tried benching it versus VNC-ing into the VMs?

If you need to network these, especially in a Domain, or how they
call these now with their rip-off Kerberos/LDAP thingie, you might
encounter Problems as Windows has some unique ID per host that would
have to be re-generated and is, IIRC, pretty much random (somewhat
like Solaris on x86).

rdiff is pretty nice to use in this regard. I had it for
differential backups of huge DB text dumps for a while. I wrote
something myself, but just saw that for most needs, rdiff-backup
should work, too.

How right you are. I'd definitely vouch for the plain fact that
nobody here has ever been entrapped into doing something by overly
complex contracts, without even knowing they were in breach.

Yours, Bernd
