Set global forwarding to PC #1 in the options block, then "override" 
that selectively by defining private.net as a slave/stub/forward zone, 
using PC #2 as its forwarder or "master". If you define it as slave or 
stub, and you *don't* want PC #1 handling queries for names in 
descendant zones, e.g. *.blah.private.net, *.foo.bar.private.net, etc., 
then you'll need to define "forwarders { };" in the private.net zone 
statement, to inhibit forwarding for that whole part of the hierarchy.
