I'd love a remote, although when I think of the kind of remote you'd use for a CD player, it still leaves a little to be desired. Sure you can stop, pause, skip tracks, but without some sort of GUI it's pretty hard to set up a playlist, and that's the main drawback of AirTunes right now -- if your Mac isn't in the same room as your stereo, you have to get up and go to another room whenever you want to queue something up.
I'd like -- and will probably not get in the near future -- a way for iTunes to control other instances of iTunes over Bonjour (Rendezvous). iTunes can currently play songs from other instances of iTunes, but what I'd really like is:
1) Desktop Mac has music library, iTunes installed, plays music to remote speakers through AirTunes
2) PowerBook / iBook, functioning as a remote control, can control the desktop's iTunes by browsing its library and setting up playlists, pausing, playing, skipping tracks, etc. All audio plays through the Desktop Mac (or to remote speakers through AirTunes)
This is much better than just hooking the laptop to the remote speakers through AirTunes -- because once you're done queuing up the music and want to keep listening to it, you can't close the laptop and put it away or it will stop playing.
