I'm considering using an AppleTV2 in my car purely for the use of Airplay to wirelessly stream audio/video from my iPod Touch 4g to my stereo/monitor. My question is this: Does airplay require actual internet connectivity or just a wireless network? Short of having wireless internet in my car (expensive), I figure I can just use a wireless router in my car to create a wireless network (without internet) and use that network to utilize Airplay. Hopefully my explanation is clear enough. Thanks for the help!
