hey there, the punchline 'does it scale' in this particular case was more referring to the client side of scaling rather than the backend. That being said, we are doing some pretty crazy stuff in the backend involving server-side JS to get things up to speed, but still need to collect actual numbers.

Neat! I hope we get to hear some details on this in the future! I was impressed with the video, can I ask what kind of machine the demo was recorded on? :)

Yeah, new details are definitely coming up! This was the first public demoing, so watch for more.

For recording, we used a 27" iMac (slow version of it), but really, it runs almost flawlessly on an iPhone and crappy netbooks.

So you're using node.js on the server? How do you store the model of the world: Redis?

Yes we're using node.js on the server-side with a combination of long-polling and normal polling (for slower devices like iPhone). I can't talk about any other server components as much of it may change. We'll post details when we think it's good to go!
