The dream must be to setup your own digital audio media centre where you could move from room to room and hear the same track being played, through any audio device, wherever you are located in you house. It's possible, it's easy and cheap to create. Apple iTunes already allows you to distribute audio to various locations, whether this is your computer speaker or a remote Airport Express audio unit. Connect one of these Airport Express devices to an audio device and you can get iTunes to send audio to any or all of these units, at the same time, wirelessly. However, what happens when you don't want to use iTunes?29 Nov 2008
