I've been asked why I don't just make these slave zones.  It seems like 
a good idea and would reduce the amount of traffic to the authoritative 
servers.

Any negatives in converting to slave zones from "forward" or 
"static-stub"?  The authoritative servers send a NOTIFY when records 
have changed so the caching servers would refresh their zones.
