I currently use my MacBook as storage for my music, but now want all my music on an Ipad and have Sonos look to the Ipad for my collection. (it's a pain booting up the MB every time to listen to music) Now I'm even wondering if this can be done. Isn't the Ipad just another drive? Can I not point Sonos to look for the Ipad instead of the MB? What would the path be?
