Fun! Here's an idea for you to consider for getting money out of it:

display the two choices "coming up" and accept person betting either on one or the other. Don't show how many people placed a bet.

When the choice is done - the part that won takes the bets of those who lost.

If a draw - like "zero", the house takes all the bets and makes a random choice.

"Make money while watching TV" - could be an appealing tagline to some :-)

--- edit: creating custom rooms could be a killer feature. Think of how a VJ can be put into the mix above - maybe leave him the %% of micropayments or points from each winning vote, or something like that.

I think this could make it.
