That was not my understanding of what he wanted. I thought he meant a
mirrored system (identical users on each box) with automatic failover
(seamless, invisible), which is neither a backup spooler (missing user
accounts) nor a peer (different user accounts). But perhaps I was wrong.
I see nothing wrong with the options you describe.
