AirPort Express - volume control?

madeinstein:

Is there a way to control volume for individual AirPort express using IPhone?

The Apple Remote application works as a volume control when streaming the music from a local iTunes libraryÿ

yes but that changes the volume of all speakers.

Don't think there's a way to control individual speakers with the iPhone / iPod Touch I'm afraid. The Audioengines have their own volume control on the back, so if I need to control only their volume, I use this.
