With a little elisp programming you could try using overlays. You can
use one overlay over the whole buffer, and you could even limit the
overlay to only being visible in a particular window (so other windows
showing the same buffer would not display the overlay's effects).

 (let ((ov (make-overlay (point-min) (point-max) nil nil t)))
   (overlay-put ov 'window (get-buffer-window MY-BUFFER))
   (overlay-put ov 'face MY-BACKGROUND-FACE))

Be sure to have a \n at the end of the last line, and it should work
reasonably enough, I think.
