You guys have to be kidding. Can you
still not get it, or are you just trying to rile me up?
The existing device, made by
Keyspan, the
Express Remote, does just this. It is wireless. Infrared, to be exact.
You plug the Keyspan Express Remote's base/receiver into the AirPort Express USB port.
*NOT* into the Mac.
Into the AirPort Express itself. (Where you can also plug in a printer to do printer sharing.) Then, you start up iTunes on your computer. (Mac, PC, whatever. Any Mac, any PC, with iTunes 4.6 or higher.) Then, using the '
AirTunes' feature, you select your
AirPort Express base station as where you want your music to come out. Now, what you've got going on is that your computer is now sending the iTunes sound wirelessly to the AirPort Express base station, through the AirPort Express base station's audio-out jack, into your stereo system. What the Keyspan Express Remote does, is send CONTROL signals back to the controlling copy of iTunes. Say you start by having it control iTunes on your Mac. So if you close iTunes on your Mac, open it on a PC, and use AirTunes to select your AirPort Express base station, the Keyspan remote will now control the PC.
This already exists. This is available now. This has to go through a firewall, so this could easily generate the message this thread is referring to. No new Apple-designed remote necessary, as there is already a non-Apple-designed solution. (Hey, look at all the non-Apple-designed iPod add-ons... They leave plenty to third-party designers. The iPod has audio recording capability, there are third-party microphones available, does the existence of this capability mean Apple will product their own Apple-branded microphone? No.)
Yes, the Keyspan Express Remote also works plugged directly into a Mac, but that is 100% separate from what I'm talking about here. Ignore that functionality for now.
