Usenet, IRC, RSS, XMPP, ... Well, still rockin'

A direct line from $random user to the on call is a recipe for disaster (ie your sres quitting) when you have many users. Engineers aren't first line tech support and those roles shouldn't be confused.
I fully understand what you're saying and mostly agree. Thoughts on having registered users of certain products having access (e.g. Domain purchasers, Google app admins [office? What is that product suite called these days?])?
Any recommendations for self hosted XMPP stuff?
