That's a really intriguing solution, cz. It also seems like you could mix different supported languages (e.g. Java if/when it's supported) through the versions mechanism since the language is specified via the 'runtime' keyword in app.yaml. Both java and python versions could access the datastore, and cron is on the roadmap. -Bill
