I'd expect that running a secondary for domB.com would be the thing to do (assuming that they may well have DNS information for internal consumption that isn't published out on the Internet). One thing to consider is what might happen if you (also) wanted to hook up to (say) domC.com. If you were to rely on a forwarder, that just wouldn't work at all, while you could secondary domC.com just as you can secondary domB.com. Beware, though: if folks in domA.com were used to referring to machine bar.domB.com as merely "bar" (from habits or code from domB.com, for example), and want to do this even from within domA.com, you may get some pressure to set up some CNAMEs within domA.com, pointing to A records in domB.com. And (to my way of thinking) that way lies confusion. (Scenario based on a real-life experience. Names have been changed to avoid embarrassment. Contents may settle during shipping.)
