There is no real such thing as the 7 2 game in NL Holdem. This is just something that the pro's decided to do since they thought the action was getting a little bland.
In cash games, as many of you know, you can pretty much do anything as long as both players agree to the terms. The most famous two are paying to see someone's mucked cards, and running the board more than once. You can do anything, such as bet on who will play the most hands, who will play the least amount of hands, who will be up or down the most or least, or even what number your thinking of. As long as the player agree, anything goes.
In regular, casino, tournament style games, there is none of these things for a simple reason, they don't encourage bad plays when dealing with player against player games. If it was player(s) against the house/dealer, then they will encourage bad plays left and right to take your money. But players don't appreciate that kind of play, and would frown upon it, making there casino loose gamblers and money.
I don't think the specific type of cash game side bet such as 7-2 would be all that a online card room should offer, I think they should offer side bets in general. Have a monitor watch over the cash game and have players make side bets whenever they want to. It would DRASTICALLY slow down the online play, but if side bets such as the 7 2 game is your kind of game, then by all means, suggest that to your favorite online ard room. But if you don't want to cut the hands from 4 hands per minute to 1 hands per minute, then I would say to let the side bets stay in the real card rooms.
Bty, I am all for side bets. Thats how I make most of my money in cash games.
