I've been using the new form for a long long time now and I assure you, BIND
hasn't had any problems with it for a long long time. :)

BIND as most all programs, should not care what the interface is or how it
is laid out. It binds to an address and port and shouldn't care otherwise.

Would I really put you in a quandry if I told you I had multiple different
media interfaces all with the same IP and BIND happily answered on all of
them? ;)
