Any luck with this yet? I was searching for an iPhone-as-controller solution when your site popped up. I would love to be able to control a game on my Mac Pro with my iphone. I am a fan of driving games - if I could use the iphone with the same actions I use with Asphalt 4 with a Mac game, that would be great. An app that could adapt to ANY game using the accelerometer and touch interface would be even better.
There is an app called QwasiPad that makes the iPhone into a multi-touch trackpad or keyboard to remotely interface with PC machines. This was a small step in a similar direction. I have nothing more to contribute because I know absolutely nothing about software. Just wanted to voice my support. Cheers
