Yes. Most of the root server traffic is answering queries with "NXDOMAIN" for non-existant top level domains, if you slave root on your recursive servers, your recursive servers can answer those queries directly (from the 120KB root zone file), rather than relying on negative caching, and a round trip to the root servers, for every new non-existant domain.
That would require configuring my caching server with authoritative zones, and it seems prevailing wisdom (at least with BIND configurations?) is to keep the peanut butter seperate from the chocolate, no matter how great they taste together, to the best of my knowledge.

No. The wisdom is to not make your authoritative servers caches. This is not the same as not making your caches authoritative for certain zones. Just don't have the caches listed in the NS RRsets. Note: You will need to configure your master server(s) to notify the caches for the zone that slave as the automatic mechanisms won't discover them. Mark
