Is it possible to add my college daughter to my itunes home share temporarily, remove her ipad, and then she goes back to school to use an existing acct or set up a new acct? Or will she have a wait period? She may have an acct for free music already but I want to show her a few things before she adds a cc to an existing or new acct. Would that work? She would be on a totally different wifi when she returned to college and wouldn't be on my home share.
