Probably a long shot, but should online gaming ever come back to the US (and perhaps this will work in other markets), maybe Zynga can position themselves as the choice for casual gambler. If they can convert a bunch of their Farmville, etc users into playing poker, it could make for some very soft games. I don't think you'll see them as the place to be for serious players who want high limits or lots of different tournaments/options, but something that even the most casual of poker players/gamblers can be very lucrative (as well as draw in low/mid limit sharks who want easy cash). This all depends on the premise that the friction from being a player of one Zynga game to being a gambling player on a Zynga game is less than being a player of a Zynga game and also joining an unrelated gambling site.
