Separating Customers from Developers using Bugzilla

How can you keep customers and developers separate from each-other?

Communication between customers and developers should be channeled through the support team. Prevent customers from seeing who is working on the problem.

Why would you want to do this?

Not doing this results in customers calling and giving the developers a hard time).

Does the solution scale to multiple products?

It's amazing how demanding customers can be. :)

How would you keep different customers from seeing other customers' bugs?

This is perhaps because the customers value their privacy.
