This is potentially amazing for me. I just started a consulting business in Japan. Credit cards are hard to come by, especially for foreigners. I need to pay for various services: domain name registration, etc, etc. At the moment I'm constrained to using Japanese companies who will accept bank transfer payments. If this becomes popular, I could buy services anywhere. There service fees are very reasonable. This is what I have been waiting for with Bitcoin (and wondering if it would ever emerge).
