Not sure about the PS3 controller, it runs off Bluetooth or USB Connections. Could this be used in an application similar to Johny Chung Lee's posting: http://procrastineer...roller-for.html for the controlling part, or is it only at the receiving state?

With this code you can't really emulate a controller to an actual playstation console, I would imagine that to be an entire project on its own. Doable, maybe, but quite challenging as the communication between the controller and the console is full-duplex at a high bitrate.
It would be interesting though to hook up the netduino to a ps2 and see if it can be controlled that way.
