split horizon and zone transfers to secondary DNS servers

Notifies are also a challenge. The two solutions are:

-Use TSIG for the notifies and zone transfers.
-Use extra IPs: on each primary and secondary, set up an IP
address dedicated to notifies and transfers for a specific view.
Your first view can use your preexisting IP but each additional
view also gets an IP of its own.

With the latter solution, depending on the situation, you might
figure out some short cuts.  But TSIG looks awfully attractive
in comparison.

The book DNS & BIND Cookbook addresses the issue.
