No (if you mean the same thing by "window" as Emacs does). There are
no buffer/window local faces (yet[1]). Faces can be frame local
though.

Yes, sometimes I'm precise 8-).

Sigh, thank you anyway, you spared me the hassle to look further.

Thank you Johan for the pointer but it's just a minor gripe for me (I
wanted to show a helper window in the frame with another background to
distinguish the windows better while saving the mode line space); I'll
stay with the stock (CVS) Emacs.

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.

Good idea, this might be the way to proceed. I'll try it, thanks.
