I generally agree having one contact person mitigates the spread of the damage. But it seems like he is asking for feedback partly because he has the role of the gatekeeper himself (at least part of the time if not all of it). Eventually everyone will hit their limit though, no matter how much support they get, or how well your coping mechanisms are. Therefore, doesn't it seem useful to find a way to ask clients to behave appropriately/respectfully? Even if they say "no", at least this opens up clear communication. (ie, if he says "I am _going_ to be jerk, live with it,", then it seems appropriate to openly be protective in return.)
