If your zone isn't very big or updated very frequently, and if you are up
for a bit of duct-tape-and-string scripting, you can sort of do this with
a couple of my tools:

Get BIND to send NOTIFY messages to `nsnotifyd` when the internal view is
updated. `nsnotifyd` is a tiny server which fires off a script when it is
notified:

Write a script to `dig axfr` the internal zone and create the external
version.

Use `nsdiff` to update the live external zone based on the version your
script created.
