If you actually want a copy of each zone in each view, you can't avoid this.

This does rule out includes; they only work for static zones.

Again, this is hard to avoid unless you burn a lot of IPs.

Have you considered a single view containing all the common zones, then 
a view per "different" zone that forwards to Provided you 
arrange your "match-clients" correctly this should work.

You may wish to investigate the attach-cache option, so that all the 
forwarding views can share cache results.

Bear in mind that the forwarding views will not see changes in the 
common view immediately, but will have to wait for TTL expiry. There's 
not much you can do about this.

Basically, there's no trick to do what you want; bind isn't designed to 
share non-static zone data between zones.
