Looking for thoughts and constructive/destructive criticism on this one:

I'm working on a project with a little indie games developer - we're making a game that ideally we'd love to be able to give away to get it as much exposure as possible, but realistically given the difficulties of getting skilled people to work for free we're going to have to try to sell it, and there's a limit to how many people will buy a game from an unknown developer.

So, having been involved in Bitcoin for the last year or so (I mine/trade extensively), I've made this suggestion:

-Distribute two copies of the game - one paid @ $10 or so, one free, but with an added component that mines on behalf of the developers using any spare GPU power whilst the game is running (perhaps throttling the mining client if fps falls below 50 or something like that).

This would obviously be something we'd have to make very clear before people downloaded the game, so that they didn't freak out about the connection activity/unusually high graphics card load whilst playing, but to my mind it's a neat way to offer something like this for free. I'd hope it even stands a chance of getting us extra exposure due to a fairly unique way of monetizing the development. The game itself will be based on Cryengine 3, so it's unlikely too many people with low-end GPUs will be trying to play anyway.

What do you think? Obviously there's the issue of people not understanding that we'd be using their computing power for profit, but I'd hope that this sort of thing can be explained online easily enough.
