This sounds like a wonderful idea, especially for people who cannot obtain bitcoin the traditional way (i.e. mine them). I would love to have my international clients pay me in bitcoins because the traditional currency (Argentine pesos, in my case) devalues too much too quickly and there is a heavy tax on inward transfers of foreign currencies like USD.

At the moment I get them to pay to my bank account in Singapore (a relatively freer financial hub where international transfers are concerned). Bitcoin would be a great cross border alternative that does away from the numerous commissions charged by this and that bank when you do multiple currency exchanges.
