There's no simple (and perhaps none at all) way to do this on the system that runs on the G1. There might be a way to do this through JNI, but it would be fragile and difficult to develop, if it were even possible. You can, of course, modify the system itself and install on custom hardware (or an Android Dev Phone 1). This route requires experience with Linux system and/or kernel programming though.
