I'm looking for a (hopefully) hosted app that would let me have my customers interact with customer support; but unlike Assistly or any of the million help desk apps out there, each user will have a dedicated rep. When they log in, I want them to see their rep's picture, email, phone number right on the side of the page, and all the interaction will be directly between the customer and their rep. FAQ, general CMS, etc are all fine as bonuses, but not the most important thing.
Anything like this exist?
