Hi nestle,
I don't see the government of Portugal (or others) creating a wallet and give us the address, to do so, they first have to admit that crypt-currencies are cool, and they can not, or the central EURO bank will be very mad

It's possible to put the list on wallet source code, of course, but we need a way to daily update that list, to do so, the project site will have the public list in a readable way and also in a computer format like JSON, so the wallet can GET the list and parse it, check any update, added organization or removed, in the case of a closed organization, or any scandal regarding that organization.
I got Your idea of dynamic destination of the donations, But I truly don't see an easy way to do it, today Nigeria can be one of the most poor countries, and we cold force more help to them, but what about 20 or 50 years in the future? Maybe they solve the poverty problem, I hope so. To do this dynamic selections we have to take the people right to choose where they want to send their help.
Regards
