TMTTR- I thought of the Casey Martin case too, but IMO that is different because golf is an athletic event and players obv. would have an edge if they got to use a cart. Martin was asking to be excused from a part of the game that takes energy out of you. (Granted, he is afflicted with an energy-draining disease already, but anyway...) A blind man being "excused" from having to look at the action himself by having it relayed to him, really doesn't give him any advantage, and none of the other players would have an advantage if they were allowed an assistant to relay the action to them. It's merely a question of "is he using the assistant for more than relaying the action." So as long as Hal is playing by the rules and not using his assistant for advice and such, he has no advantage.
