• node.js
• ruby - just to server static files. Can be anything

git clone git://github.com/makoto/node-websocket-activity-monitor.git

node server/websocket-server-node.js/server.js

• Tidy up file structures
• Remove ruby (please someone let me know nice ways to server static files from node.js)
• Write a blog post

My bits and bobs are MIT, but be aware of others. Especially RGraph has its own license, and you can not use it for commercial purpose, I think...
