I am sorry if this has already been covered, but I can not seem to find a clear answer to this. I plan on purchasing an apple tv to use primarily with my itunes library. I will not typically be streaming anything locally as I have itunes match and a wide band connection for streaming video. My goal is to configure a setup where as long as the apple tv has internet, no one has to stream from a computer (except itunes movie which I will end up using the ipad for anyway). My roommate also has an itunes account and will want to access itunes purchases on the apple tv. If home sharing is properly enabled, will he be able to access his purchased music and tv shows on the apple tv without his computer being turned on?
