I like this idea. I currently have a full-time job and am doing 15-20 hours of consulting a week so my projects are more like "late at night and weekend nights" projects. This appeals to me.
I would like to see some type of standard agreement around this along the longs of "I spent 2 hours contributing code that you're using, I get 1% stake if this thing every gets sold / gets funded".
I would prefer it if the agreement were "the code will be released under the GPL or BSD or MIT licenses and the art will be released under a Creative Commons license". That way there's no arguments later on about commercialization of it because the licenses would allow anyone to commercialize it. So your work helps the world, helps the other person and it helps you if you want to start selling it.
