one angle not addressed is there could be a social contract and relationship between the donor and the recipient. This currently assumes a single transaction, but what if the recipient had a way to pay it back and/or pay it forward? If the donor had the opportunity to view the results of the donation, the satisfaction from it and the relationship obtained makes the sacrifice worth it. If there was a system that helped to track it with the various privacy and other concerns, that would be so awesome!
