I am exploring for someone else. The idea is to use the ATV as a physically connected device to a classroom projector, and then use AirPlay to mirror an iPad desktop. The instructor would otherwise not be in front of the class, but wandering around the classroom. The act of showing media, drawing simple line illustrations, equations, etc. and wirelessly having it transported to the ATV and projected on a projection screen in real time. My concern, through is the output video resolution. I understand the ATV may be matching best case iPad desktop resolution vs. the lower commonly offered HD resolution, but I am a little concerned over 720P (in 16:9 aspect) being projected onto such a large surface. At this point, I am wondering if one should wait for higher desktop resolutions and ATV capabilities to present themselves. Also, I am curious as to secure setup so that the bored and capable students don't go hacking the in-class activities.
