I'm probably biting off WAY more than I can chew here, but EVERYONE who has (or it would seem has heard of) an iPhone or an iPod Touch thinks this is a good idea, yet NO ONE appears to have taken up the challenge.
So how's it going?
I finally got LinuxMCE installed under VMWare. Doesn't do much yet, but installed and went through all the set up and can play with things using the arrow keys on the keyboard. fun. Running it under Mac OS 10.5.8 on a Core Duo 20" iMac with 2GB Ram.
If you install the developer tools on mac os x (may have to get a free developer license from developer.apple.com), there is a simulator located at your-HD/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app. In case you do not have a touch device. I currently do not, but plan on getting one shortly, when the new ones are released.
I will pitch in a few lines of code etc if I can on the project, but till then, there is always the web browser built into the iPhone / iPod Touch.
I will have to do some research on how the tilt API's work, and if it is just sending messages to the server (right), then it shouldn't be that hard to set something like that up for these devices and get it working. Can even think of a few clever ways to keep things quick and simple, which is the point
