Is there anyway to control the iTunes volume whenever iTunes is open with the Apple Remote? I use AirTunes, and I'd like to just have to use one remote rather than two (i.e. using my hi-fi remote for volume). Ideally, whenever iTunes is open/active, when volume is adjusted on the Apple Remote, it will adjust iTunes. Whenever iTunes is closed/inactive (i.e. paused/stopped) then the Apple Remote will control the system output volume as it does by default.
