That would be a great project indeed, unfortunately I don't have the time or energy to do it myself. But if somebody does it, I will definitely use it and promote it.

You can code yourself new betting platform, with Intrade-like
features You wish, but for Bitcoins.
Tho you'll need to convince people to trust your site
somehow.
I hope , that in the not so distant future we'll have
distributed betting system, without necessity to trust
to server operator.
