Team, any comments as to whether the following would work: 1. Apple i-Touch sends on-board mp3s via WiFi - Airport Express to amplifier? 2. Apple i-Touch sends mp3s from network hard drive via WiFi - Airport Express to amplifier? 3. Apple i-Touch sends internet radio via WiFi - Airport Express to amplifier? Basically, am wondering whether the Apple i-Touch can be used as a source / controller over WiFi.
