Let me explain a little more what I want to achive
This is for my grandparents, currently they have a mac with iTunes and 2 apple tv 2's. What I am looking for is a speaker system to go in a room with no tv in it and for them to be able to play back their iTunes music without having to go into the study and touch their mac which is always left on.
is there a device that can do this ? One last note they do not own any iOS devises.
I don't think this is possible without an iOS device. You might be able to get a cheap used iTouch 3rd Gen to use for this. That way they could also travel around the house with it and control the ATVs also.
