This might be a real duh question but I haven't had much luck searching. I'm wondering exactly how airplay works. Does it (or can it) work directly between the iPhone/iPad and the Apple TV or do they both have to be on an existing network. I ask because I always travel with my iPad. Some nights I go out but some nights I just want to hang out at the hotel and it would be nice to watch my movies on the TV instead of the iPad. Can I throw an ATV in my suitcase and and use Airplay or will it not work (assume there is NO network (wireless or otherwise) available at all, to keep it simple).
