Personally I think it's a horrible idea. Poker has been played in many variations for a very, very long time. Regardless of what variation it was, there was always the concept of someone winning an amount of money after a round of play. I doubt there were very many saloons in the American west in the 1800's that had kill pots. People inject modern crap like this and live straddling into the game and ruin it for the traditionalists.
