Your biggest issue is that unless you are using separate IP for each
instance of bind, you will have problems as both will by default 
need to use port 53 for DNS service.

Perhaps you want to investigate the use of Bind9 view function
which lets you show different data to different clients.

The ISC homepage for bind is an excellent resource:

As is the "DNS and BIND" book by Albitz & Liu from Oreilly.
