Nice little write up (might be well out of date) here - http://www.codemag.com/article/1210051 and here - https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_server

It would be nice if we could get a cross-platform solution working i.e. .NET client and server and a JS Client and Server, but all of them being interchangeable.
