I need to completely isolate two or more users (call it multi-tenant if you wish).

So far the most important thing is the address book. I do not want one user to be able to see the numbers that were used by some other user.

Is it possible to limit the shown numbers to the ones the user used in the past ?
In case this is not possible, can I disable the address book functionality all together (short of editing the html/php files) ?
