I have got myself an Airport Express and am streaming tunes to a hifi in the kitchen. It works really well with no network stalling. Before I go and buy more, I would like to know if you can stream to multiple APEs at the same time. Or is it limited to a single APE at a time? I would also like to listen to music on my iMac and the APEs at the same time. For some reason the music doesn't at the moment with my single APE. Is there a hack to get it to play on both at the same time? While I'm on the topic of iTunes, is it possible to control the playback of iTunes from another computer. Let me explain... I have an iMac with all my music library on it in the study. I also have a PowerBook which I would like to control the playback of the iMac library from the kitchen. I can (at the moment) share the library which the PB connects to and then connect to the APE in the kitchen. But I would like to be able to turn off the PB but leave the music playing from iMac. Essentially using the PB as a remote control and not as an iTunes client. Can this be done?
