We are part of the team that develops palava.tv: A simple browser-to-browser video platform. It is based on WebRTC, the new web real-time technology that can be used in many creative ways! We learned a lot about WebRTC and want to assist you building your own video/audio/real-time enhanced apps.
signaling.io will be a service that handles the signaling part of WebRTC for you. You won't need to build/host a signaling server yourself and can concentrate on building web apps actually using WebRTC!
