I've seen it done.. There are lenses that are curved so much that the projector can be mounted on the ceiling, just a few feet away from the wall, and pointing sharply down and it will still project a square image. Those are probably pretty expensive. If you're using the regular lens on the projector, just position it as far away from the wall as you can - it will work with keystoning and the proper angle.
5 to 7 hours seems fairly normal for videos that are on all day on a loop in a gallery. Multiply that by 30 days for the show and that's how it usually works.
