First of all, my G4 does not have bluetooth, granted, I can easily borrow a usb dongle from work, bu then, I don't have a bluetooth phone. I DO however have one of those airport express keyspan remotes, which can be hooked directly to my G4 to contorl iTunes. Heres the thing- I would not want to mirror the displays. I want visualizations to appear ONLY on the projector, for I will be mixing music from my collection with mix cds that the groom at this reception wants me to play, so I must be able to mix and mesh tracks together on the fly, and I can't do that with any kind of remote device. I think I'll just dig a secont monitor out of my personal stock and ry it out myself. I'll report later on my results.
