stub zones

Not quite, Bill.  You point the zone at a different name server, but 
_your_own_nameserver_ still does the iterative queries to make things 
happen.  It just queries a different set of nameservers than would 
happen through normal delegation.

The only recursive query going on is from the client to your nameserver.

Since you asked the question, what would you propose as an alternative 
for folks running multiple sets of nameservers with different info on them?
