I would love to take on this project. It's interesting, unique, and lets me play around with an API on Android that I haven't gotten a chance to yet. The only issue is that I don't have any Bluetooth HIDs to test with, I don't have the money to go out and get one, and the Android emulator doesn't support Bluetooth, so I can't hack my way around it to test. If you already know what kind of events/data to expect from the devices, or wouldn't mind helping me get that information, I would pour my heart and soul into this project. And if ever you're not satisfied, or it breaks, I'll fix it or your money back.
