I waited to suggest this based on whatever additional information you
provided, but it sounds like this could work, with the condition that you be
able to identify the IP addresses (or better yet, ranges) that the different
categories of process will be assigned to in advance; or that you could
configure named.conf (or an include file) on the fly. And of course, all
THIS is presupposing that you can get both views (inside and outside) on the
same nameserver, that is available to both sets of processes.

So, not trivial, but could possibly solve your problem.
