In my family we have 3 different iTunes accounts and I was thinking of getting the Apple tv but I'm unsure of how easy it is deal with different accounts. One specific question is can all the iDevices use AirPlay to send music and apps to the Apple tv regardless of what account each device is hooked to. And when you get the Apple tv do you log in to one account on the Apple tv itself? Does iCloud automatically bring in some data? And what about photo stream? And what account do you use to buy and rent movies/tv shows? I guess my confusion stems from my assumption that when you get an Apple tv you log on with one iTunes account? Can you log out of that account and switch easily to another account? Do you need to switch accounts to use AirPlay with devices hooked up to different accounts? I suppose anyone with multiple iTunes accounts and the Apple tv can share their experiences and any difficulties they have experienced?
