Possible to condition a view based on the interface the query comes in on?

Right, listen-on is for the server as a whole.

To control which view is used to answer a query based on the server
address, use the `match-destinations` option. For details see

Don't believe everything you read on the internet :-)

Yes, you can have different RPZ configurations in different views.

Another trick that's useful for the kind of setup you are planning is to
use the `attach-cache` option so that your views can share the same cache.
This improves performance and reduces memory usage. It still works with
differing RPZ policies because RPZ only affects the responses sent to
clients; RPZ doesn't change how recursion works or what records are saved
in the cache.
