Chromecast: Cast movies on your Desktop Computer

As the title says... if you have a movies on your desktop computer, you can now cast them straight to Chromecast.

This is highly efficient, as there is no encoding/decoding taking place. It streams at full quality, with no lag. And since it is a Chrome app, it works on all platforms. No binary installation necessary; it will be available on the Chrome store.

Technical Details
I spent tonight writing a mini HTTP server in JavaScript that runs in Chrome. Full featured enough to handle requests and stream movies.

Yes, that means there is a web server running in my web browser. I'm insane.
