It sounds something like the stock market to me. I'm not sure what you mean by accountability, do you mean that someone could do a runner after using the service and not pay out. If you did base it on stocks and shares then that wouldn't happen. I don't personally understand how stocks work, but i recall it was invented by betting on whether ships would return from a dangerous voyage or not, and as a way of spreading the cost and spoils. Surely it's possible to bet on a relationship in the same way, and those who bet the most accurately would benefit the most. then you look at your odds and check the match out.
