If you have two daemon on the same machine, you'll have to hack the
source code. Bad thing. Just use two machines, one with the public DNS
and one with the private one. The private one is configured with the
forwarders and slave parameters pointing on the public DNS. Now
all the internal hosts can resolve any address but the internet will only
see what's in the public one.

Cheswick and Bellovin's book speacks of this scheme as well.
