Change the View Directory

How do I change the view directory?

My situation is: I am creating a CMS for personal use, that I will
also have a public view for people to play with the CMS without
harming the DB. I'm thinking of creating a new app that takes from a
different DB, but uses the same views (so I don't have to duplicate
anything).

I suppose I could use the same app and tell the controllers to take
from the dumby db if a test user is logged in. But I feel like I would
be safer this way.

Any thoughts?
