you can also use attach-cache directive to share a cache betwween 
multiple views. If your views only differ by loaded zones, that should 
not be a problem.

If it's not possible, you (or the OP) can surely configure 120 or e.g. 
million real or virtual machines to provide the DNS service.  That is 
just what views do within one BIND process.
