Hi, I'm in the process of making a game for Mac OS (sorry, OS X) that requires a multitouch input. Right now it just uses the built in multitouch trackpad on a MacBook Air or Pro, or a wireless magic trackpad or magic mouse if it's running on a desktop computer, but I'd like to make it so that even more people can play it. I'd like to make a controller app for iOS devices that will let them connect to the Mac app and send touch coordinates to it. If multiple iOS devices could connect at once to the Mac app, that'd be superb. Suggestions on how to get started with this? Googling around I found suggestions to use Bonjour to get the iOS device and the Mac to "see" each other, but I don't know what to do once they "see" each other to "talk" to with each other. Thanks!
