Hey Jim, If you mean between a client and GAE maybe you'd find the Channel API useful. If you mean between two tasks running on App Engine how about using 'markers' that you can fetch. Then, once all are present and in a 'completed' state, fire off the next step in the process. In other words use a push pattern instead of a pull pattern.
