There are 2 Apple remotes, one for things like Apple TV, which you could use in place of a Wadia+iPod; the other remote is the app for the iPhone/iTouch works via wifi. You could sue the second to control a laptop feeding a DAC, again instead of a Wadia+iPod. I think thats the 2 uses?
Again welcome to head-fi. Warning, you should be ok with the dynamic crowd, just be careful about those Stax guys, they get pretty spiritual about their headphones.
