iPad 2 / Apple TV Document Camera Setup

Those interested in setting up iPad as document camaera with iPad 2, we are trying this solution from:  http://www.modularhose.com/ ... We will put it into some classrooms next week.  We are not fans of the clamps sticking off and are working on some other possible solutions.  The platform is nice as it is tough, flexible, etc.  We did have it working with 1 leg so to speak but it is much more functional with two.  Right now we are very pleased with the picture quality and all of the added functionality that you get vs. document cameras.
