Thanks for your welcome Christopher, and let me say... what an amazingly speedy response. I'll think I'll like it here :)
1. Ok, that was what I was afraid of. But let me rephrase the question then. Is there a list somewhere with which protocols are in place today for iTunes? The Visualizer template, do that contain all of them already?
2. And for future reference, is there a list with other applications protocols that Apple provides? Maybe I will hit the same snag when doing something for iphoto, iMovie etc.
Regards,
Daniel
