Hi-- I've been considering getting an Airport Time Capsule, but can't for the life of me figure out if it can be used as a wirelessly accessible external hard drive in addition to being an automatic time machine backup drive. Could I smoothly, say, move 1/2 of my itunes library to the time capsule and access the songs through iTunes? Sorry if this is obvious, but it seems that there are conflicting answers to the question of external drive functionality even on Apple's discussion boards... User stories/experience appreciated. Thanks!
