Freak, an idea we have used for dealer's choice is that who ever calls the game, that game is then played for the entire orbit +1. The game starts with the person who called the game, each person will also deal that game and when it comes back to the person who called the game, they deal the game the last time. When that game is complete the next person to deal calls the game and it continues like that.
So, if there were 6 ppl and you started dealing and called hold'em, you would deal hold 'em, the other 5 would also deal hold'em and when it got back to you again you would deal hold 'em. The next person to deal could then call his/her game and it would be done the same way. Basically who ever calls the game deals it twice before the game switches.
