Bind views may do some of what you are after:

http://www.zytrax.com/books/dns/ch7/view.html

You can return different results to queries depending on the origin of the
query - even if it is for the same zone.

E.g query from Internet for "mail.acme.com" => 200.200.200.200
query from Internal host for "mail.acme.com" => 192.168.1.1

I am not sure I understand the bit about "part of the zone is defined in
one NS and the rest on another" ..
