BIND Authorative forwarding caching server

[dan at nameplanet.com]

I dont need to worry about recursion.
I am running BIND with DLZ - a database driven solution for thousands
of zones, which are contunously changing. It dosn't perform to well,
but the functionality gained from doing it this way is immense. Rather
than having many DNS servers, I was hoping to have some
caching/forwarding slaves that all forward to a couple of masters, so
that each slave wont need it's own extenal database.
