Okay, from our discussion in the other thread, I now see that you're talking about a way to specify a song directly to the receiver without messing with its user interface.

Well, now here's where I get confused. You're asking for this kind of support as well as the gentleman who started this thread, and I'm not sure why you would want this.

The Receiver is designed to let you play music in a room away from your computer. If you're in the same room as your computer, why don't you just have the computer play the music and leave the receiver out of it?

Why would you want to remotely make the music change at the other end of the house from the computer? Surely you would want to select the music from the room in which you were listening to the music.

It's this same reason why (despite my multiple mentions of it here) I never tried running Displayserver on the receiver. I never saw the need for remote controlling the player.
