I don't know if anyone has done this before. I was in Home Depot hardware store just looking for ideas (for my future NEC150), then I stumbled onto these ceiling mounts for TVs, you can place the projector on the platform plate which can support up to 100 lbs anyway, you don't even have to invert the image. All for $50.
If only I can figure out how to run the wires up with approval from the wife.
