I saw a really cool design when I was at a car show recently. They had a 4 post lift with castors and what they used was a small "panel" of sorts that was attached to the ceiling. When the 4 poster was in use the panel came down from the ceiling and it provided air, 4 post power and another duplex plug for additional tools you'd use. When the panel wasn't needed it was pulled back to the ceiling by a simple cable. It reminded my of the coil style work light idea. This system seemed perfect for those 4 post installations where a wall isn't close by to attach the cable, air etc.
FWIW, my 2 cents.
