You'll need some custom optics and software. The FOV of that projector is goo narrow for a panel/subpanel mount, the focal distance is too far out, and if you place it overhead, you'll see the glare from the lamp. But you could probably cobble up a camcorder fisheye lens to compensate for the FOV, and maybe that would fix the focal as well. All you need then is an Open GL 2 shader that distorts the image to be the inverse of the curvature of your canopy.
Just don't move your head around too much.
Personally, I'm waiting for the big leaps in augmented reality tech to go mainstream, like glasses that display information superimposed on your normal view, or a few years down the road, project it directly on your retina with microlasers or lensed LED's.
