Russell,
I can't take a cut of the pot or ante as that will convert me into a gambling site, of the type that are illegal in the US.
I'm all for letting people play for free but I would like to make at least enough money to support the site and cover development cost.
I have an idea for a Mac/Win/iPhone client built with Unity [1] but I need to launch something first and let people kick the tires. This is where the Flash client comes in.
What about letting people replenish their balances, for a fee, e.g. pay $5, get $1000 in play money?
