Late getting back to this... if he has the option of acting as a slave,
and both parties are willing to do the work (and it might be trivial,
but if there are lots of zones, it may not be), then I'll agree.  If not,
there is nothing inherently "broken" about using a forward zone (and yes,
Bob, one entry will cover all subdomains).  Interacting with private partner
networks is what it's there for, and while some may misuse the feature, and
others just don't like it, that's not to say it should be avoided at all
costs.
