apprtc.appspot.com is a webrtc demo application hosted on App Engine. Developed by Google and Mozilla, it enables both browsers to "talk" to each other using the WebRTC API. To try this yourself, you’ll need Chrome 25 Beta and Firefox Nightly for Desktop. The source code can be found here: https://code.google.com/p/webrtc-samples/source/browse/trunk/apprtc/ Interop between both browsers is a snap thanks to a Javascript adapter library.
