Fast forward to yesterday. I finished implementing the deployment platform for Node.js on top of Google App Engine (the web front-end) and Amazon EC2 (the back-end). Like Heroku, it has a git-based workflow.
The web site address is https://worqshop.appspot.com/
I've written a quick start guide on the web site. If you want to give it a try, just sign in with a Google account. Let me know if you encounter any problems.
Any feedback is much appreciated.
