I agree with this. Is there such a thing as an open source charity? Or is that just a weird question?
Yes it's called Devcoin Seriously though - if we could build partnerships with for example Ubuntu - that is probably the way to go. Start canvassing open source organisations / movements / groups.
Would open source medicine be something to consider? I only just read about them maybe a week ago and tagged it for research for a future article, so I cant speak to their suitability, but the idea seems to fit.
