title: WebRTC: Implement peer to peer chat over LAN
body: <p>I want to implement webrtc video peer to peer chat over lan network. The MDN states that a mediator server is necessary for the application to communicate because of multi user chat. But, If only a 2 people chat is to be implemented, then is there a way to do so without mediator server in Nodejs. The application to be made, will function over LAN.</p>
