Eh, it wouldn't bother me too much to downconvert the ALACs into 256K AACs or 320K MP3s (just time and storage, who cares about that!), but the trick is finding the dock connector transmitter and receiver pair that would work. From what I know, the iPhone and iPad do not properly support A2DP, and I don't normally use those for playing music in any case.

I am the Doctor, and THIS... is my SPOON!
