Audio Blogging by Phone to the US

Very cool. It works. I tried the audioblogger service that comes free with Blogger and it's great. Especially if you're in North America. I had to call a US number from here in Australia so there's a cost involved, but I got straight through, spoke my message, and it appeared here below seconds later! Astounding! I know hundreds of people do it every day, but this stuff still blows me away. If I was travelling in the US this would be especially useful. Now dear Blogger people, how about some international numbers for this same excellent service? One in each continent would be good for a start.
