I have recently been developing a kernel extension that can emulate the HID control reports that the Apple IR Controller sends to the system. I have been able to get it to work for some commands, but there are still a few bugs that I need to work out. I hope to have it done and working very soon!
I'd rather not make a release yet as one of the bugs limits what you can actually control with it. I don't want bad copies circulating until I have something that actually does what it is supposed to do.
Thanks goes to eveyone that has sent me AppleIRController HID information as I wouldn't have gotten so far without it (I don't have a remote)! I hope to release this to the community very soon. I will be posting the status of this project as things develop.
