This demo is based on WebRTC. It provides similar client and server, with minor changes due to different asynchronous HTTP calls made in the webrtc client.
This demo will not be modified, but it can be a good starting point to anyone who wants to test webrtc features.
It works in Google App Engine, or with the GAE SDK in localhost. Just clone it and run:
dev_appserver.py $PATH_TO_WEBRTC
To upload it to GAE change the app name in app.yaml.
