FYI, Armin doesn't mention it in his article but the guys that built Battlelog, ESN, is releasing the web framework behind it: http://www.esn.me/product/planet/ http://www.esn.me/product/planet/. They also have a great service, BeaconPush similar to Pusher, only better IMO. Both because it supports the notion of users and also it has both a Flash websocket and XHR long polling fallback where as Pusher only has Flash websocket fallback (believe me, this matters, I've tried both).
