Nice job! I just tested it out and it works great. I see you're using google app engine, I'm building a couple of apps on it and love working with. My platform of choice for sure.
Thanks! GAE is definitely a great way to get something up and running fast.
After spending a few months with RoR though I definitely am enjoying writing in Ruby more so than Python. I might try JRuby next time I do something on app engine - http://code.google.com/p/appengine-jruby/
