I saw a post on the OFPDR forums where a guy uses a think called a XIM to control squad orders for the 360 version of OFPDR via a laptop keyboard (multiple controller inputs mapped to a single key press).
I've done a quick google on the 'XIM' as its called but the websites are all the wrong side of our firewall. Not that I'm at work you understand...that would be morally wrong.
Anyway my point, if there is one, could this potentially be used to use a PC joystick on the 360? In conjunction with the laptop keyboard you'd have all the buttons you'd need. Anyone not suck behind a draconian firewall want to check it out?
Oh and I think its got adjustable deadzone settings.......
