Can't wait for that to be released. There are so many applications that can take advantages of mapping and location, I still don't get why Apple has not shipped it included in the SDK....
Nice one, all I needed. I had developed something similar for http://www.templeet.org/ and did not want to write it again for Ruby. However my version was probably much longer to write, did not have hpricot :)
