I've had good luck with both ordered dithering and dithering by error
propagation (sorry, can't remember the reference) - the latter having
been discussed at length in this group not long ago.  I've used the first
method for both 8->1 and 8->4 bit conversions and the latter for 8->1
and some rudimentary color dithering (8->?).  Check out dithering in
the literature.  If you come up dry, drop me a line.
