So I have seen on the Drobo and a few other NAS systems they offer the iTunes service. Now from what I understand they offer a "shared" library and has some limitations, like I cant stream to the aTV with it, etc. But, if I were to connect a USB drive to my Time Capsule and run it as a network drive, would the TC serve up the iTunes library in the same capacity as those other NAS systems or does the TC not have that service?
