Maybe I should clarify: I'm wondering if the iPhone Remote.app will be able to control the iPad iPod.app when it is connected to a sound system? Say you leave your iPad docked in the living room to your sound system during the day and want to be able to control it from the couch or the other room. Can the iPhone control it?
I know that probably nobody knows right now, but its an interesting idea. Surely this will happen eventually. I don't have my Mac hooked up to my big sound system in the living room, just to my small Bose computer speakers in my office. I also don't have an airport express. So if I leave my iPad docked in the living room anyway, I'll probably hook it up to my sound system. Controlling it from my iPhone would be nice.
