Running both a cache-only and an authoritative server on thesame server

No but you set notify-source and transfer-source to the IP of the NIC that you want to handle the view.  That effectively restricts the traffic for that view to the specific NIC.  (Note this is the NIC's internal IP not any NAT ip you might have redirected to that internal IP.)

The important part seems to be "on a secondary IP" and afaik listen-on
statements don't work inside of view statements.

That leaves you with running two seperate instances of Bind on the same
server.
