A WebRTC Signaling Server implemented with WebSocketshttps://github.com/palavatv/palava-machine
PalavaMachine is a WebRTC signaling server. Signaling describes the process of finding other peers and exchange information about how to establish a media connection. It works together with the palava-client.
The server is implemented in EventMachine and Redis PubSub and communication to the clients is done via WebSockets. See it in action at palava.tv.
