Brainstorming

I've been thinking a bit lately about constructing a system using cards instead of dice. I know it's been done before, but mainly with tarot cards, which I don't have and don't know how to use.
I'd like to have task resolution take place through hands of poker. Not sure exactly how it would play out, but I have a few ideas on what i would like it to accomplish. I'd like the damage/margin of success to be accomplished through the bidding phase of a poker hand. I'd also like at least some of the experience points to be given out via winning those bids. Any ideas on how this could be handled?
I don't know exactly what setting this system would be most ideal for supporting, but it would have to involve some sort of inter-party tension, since I'd like to include the character creation idea I pitched for Josh's supers game. Kind of keeping with the bidding idea.
Obviously, none of this would work well on-line at all. Fortunately, I'll be back in Mass soon. In fact, I'll be getting in the car tomorrow morning, and reach Pittsfield on the third, then Woburn on the sixth. This is a permanent move. I'm done with AZ. Shaking the dust off my feet and all.
So, lets brainstorm, and then arrange for an actual trial run in meat-space in the near future.
