This is Chrysalis, a websocket-based MUD client.
It is now nearly ready for production use. To install on your MUD, just serve these files, altering settings.js to have the websock URL.
Because websockets use a HTTP frame rather than being raw sockets, you'll need to run a websocket proxy on a server. I have been using websockify (github.com/novnc/websockify)
Open issues: the width detection doesn't seem to be quite right should i use jQuery more?
