Folks should also look at some of the DNS appliances (I know, this is "extra hardware"). Although the usually run BIND, they tend to be fairly optimized and have extra management functionality that may help with the rate limiting (if not, its probably a feature request that the vendors would entertain rapidly, as there's some pretty intense competition). Some folks to talk to - Infoblox and Bluecat.
I'm not sure what you mean by "optimized" here, but I suspect that the only part optimized is the user interface for configuring per-client policies that still do not scale, but I would be glad to be proven wrong.
If you have really large DNS rate requirements, I'd consider talking to Nominum.
I agree with you there; but that's sort of a given :) matto --matt@snark.net------------------------------------------<darwin>< Moral indignation is a technique to endow the idiot with dignity. - Marshall McLuhan
