I don't know what the poster's reason is for having two DNS servers but
have a look and bind 9. Do the opposite. Have one DNS server act as two. 
With views you can have the outside world see one thing and the inside 
world see another.  That's how I'm set up. One view is called external 
and when folks make a query to it it responds with what I've told it. 
But when an internal machine makes a request the DNS will respond 
differently. It all depends how you define the views.
Way nifty and the systems are none the wiser. :)
