I suppose if getting to the wall switch turns out to be more difficult than anticipated I could get lazy and drill a hole in a discrete corner of the ceiling (there's a built in desk in the corner that would hid it well) and just plug the thing in to a wall socket, but that's pretty sloppy and I'd rather not.
