the SortFirst/SortLast cluster windows do something along those lines,
each render node produces part of a final image that is composited on
the client for display. While those work with only transmitting colour
(and depth) data, I don't see anything that would prevent transmitting
additional buffer contents as well - you are going to consume a lot of
network bandwidth though.
