Joshua, Great tip! I'm wondering if there's a way we can better surface App Engine's versioning ability as a great way to stage a new release of an application.
For those not familiar with what Joshua is talking about: when you change the version number in your appengine-web.xml or app.yaml file and deploy your application, you can access all versions of your application at VERSION.latest.APPID.appspot.com <http://version.latest.appid.appspot.com/>. All versions of your application will have access to the data store, and you can cut over from a production version to a new release with the click of a button in the Admin Console.
