I too have an app designed and being developed with the Channel API. Seeing the new pricing plan, GAE is a no-go. It will be redesigned to run in AWS.
My plan is to use Node.js for push. A single Node.js can support ~100K channels. Run multiple Node.js processes for further scaling. Run a Membase(or Memcached?) as a PubSub registry to map a channel id to the Node.js server. Publishing to a channel involves looking up the Node server servicing the channel from Membase, and submit the publishing data to it. The Node server then turns around and push the data to the browser. Node.js is pretty lightweight. I plan to try out with a micro EC2 instance ($12/mon for reserved), and see how far it can go.
