The thing I like the best is the live preview URLs, especially across devices. I caught one of your live demos of this recently, and was blown away.

What's the library/service you're using to do this? I recall finding a reference in the JSBin source, but please remind us. I would love to get live previewing working in my web design web application, Edit Room, which also has shareable review links. (link in profile).

It's called "the spike", but it's nothing more than EventSource triggering an event to refresh or inject.

The client code (for both remote rendering & codecasting): https://github.com/remy/jsbin/blob/master/public/js/spike.js

The server side: https://github.com/remy/jsbin/blob/master/lib/spike/index.js

Very simple, but requires an event based server - so Node was the obvious choice for JS Bin.

Thanks! Will check it out.
