I take it you have seen the replies Markus Kuhn got when he asked in one
of the X lists (might have been xpert or xfree86, not devel) a couple of
weeks ago ?
At least on devel, you are more likely to get useful answers if you
ask specific questions.
I haven't much experience of the input side of things, so can't help
there, although there is an input plugin interface.
Two thoughts to get you started on the output.
xc/programs/Xserver/miext/shadow is a shadow layer, which is
used by some drivers as a memory framebuffer, and every now and then
the bits of the screen that have changed are copied over to the hardware
as rectangles. This might be good if you have very few drawing primitives,
or reading back the Sun Ray frame-buffer is slow.
Not part of XFree86 (for licencing reasons I think) there
is an X video driver which renders to a VNC viewer instead of
local hardware. I believe it has a home page on sourceforge.
