Making money by playing a game

Hey guys, I would like to hear you opinion on one thing. I would like to make a game where players could make money by playing, to be more specific, by selling items they find/create to other players , just like diablo 3 is planning to do. The problem is that to make this work with real money (dollars) is beyond capability of indie developer or even smaller company, because problem with laws are enormous.
I had an idea how to go around this problem few days back. It is far from ideal solution, but it might work if enough people are wiling to try. Solution is using bitcoins instead of real money. If you never heard about it before, it is virtual, distributed currency that can be used (and is used) for fast, unmonitored international transaction. There is lot of place that accept bitcoins, even some games. And you don't have to pay any fees
You can exchange it for real money in one of many exchange sites (not sure what is official name), for example https://mtgox.com/. Downside is that not everyone is using it and most people probably would not bother starting using just for the sake of one game.
What I would like to know is, did you hear about bitcoins before? would you use it in game? both for paying and getting paid. I think that model where I accept dollars as payment from player and pay in bitcoins to those who wish to withdraw money should be relatively easy to make (or at least doable)
