Poker Bot?

On Poker Stars there was a player who was multi-tabling - 17 tables.  He seemed like a tight, aggressive player and winning, and after putting him in "find a player" for future reference - the drop down showed that he was playing on 17 tables.  His decisions were fast the (avatar which pulses)  pulsed no more than twice before he made a decision. Only when posting a blind, did he take time and his avatar pulsed more than 5-6 times before he posted his blind.  All this was at the 2-4¢ hold em limit, full ring games.  How can you play 17 tables at once?
