Use both !
Implementing internal roots will give the possibility to have
both domains active at the same time.
And, of course the both domains you use could be present in both
nameservers. ( if you are talking about dispersed organsisation in
many locations 2 nameservers in total is too low. I'd say at least one
per-site, caching only could do.

Sorry about my e-mail address, but i'm trying to keep spam out.
Remove "icke-reklam" and it works.
