Okay thanks for all the suggestions re Crowdsourcing etc. I've just put up a page on http://www.indiegogo.com/Banzai-Bash to do exactly that.

Re free - if I raise the money to cover my living costs, I'll make the game open source. You'll easily be able to spin it up on a VM/cloud server (or your home comp if you're brave/foolish) for free! What's better, is that you'd be able to modify to teach your own language/project.
