I was playing around with the Apple Remote in my BootCamp partition yesterday, and some of the multimedia keys work without doing anything special. However, JUCE only supports play/pause, stop, fast forward, and rewind keys.
I’ve messed around with the library, and it only takes adding a few lines in a handful of files to get support for more keys (like volume up/volume down). So, err, yeah, I guess that’s my feature request: more MM keys.
