What is the use case for this?
Is it just to make it easier to send anonymous donations by typing in Pay To: "redcross.org" instead of copying&pasting a bitcoin address?
If something like that were implemented, seems like it would just invite the same kind of abuse we see with misspelled-domain-squatters-- setup a domain record for "redcros.org" pointing to a non-Red Cross bitcoin address and take advantage of people's fat-fingered misspellings. One big advantage of bitcoin addresses is that they have a built-in checksum, so if you misspell them (or screw up the copy&paste) your attempted transaction will be immediately rejected.
