My ceiling is about 6' 6" from floor to the ceiling tiles.
Right now my PJ is mounted inverted and 1/2 the projector is up into the space where one of the ceiling tiles was located. The lens is almost flush with the ceiling tiles (so 6' 6" off the ground, inverted).
The projector is then tilted up a bit towards the ceiling tiles, and I use keystone correction to square up the image on my 106" screen. When people look at it they go "Isn't that projecting..uh, onto the ceiling?". Then I explain about the image offset. It looks, physically, like the lens is pointing up towards the ceiling at a shallow angle.
When projecting, the top of the image is about 5" below the ceiling tiles, squared up with my screen. I think its like 24" off the floor for the bottom of the image. About as big as I can go with a 16:9 screen with this ceiling height.
No problems at all, tho I do have to use keystoning. Some people hate it, others, like me, can't see any noticible difference in image quality..but I'm guessing that varies from PJ to PJ.
