Why are you all trying to make mining accessible to those who can't afford it? Why not focus on building a BTC based charity? Build the use of BTC and not the mining of BTC. It's hard to buy things with BTC now but it is possible to trade BTC within the community, like a real currency.
So trade for services or community-created objects that can be provided to the poor. If all you people think about is mining, you can't advance BTC as a currency.
Maybe we can work with an NGO for logistics of the final service/product delivery. This might shift the image of BTC from bad (silkroad) to good (benefiting society).
Otherwise, BTC is only useful for llama socks and speculators.
