Well, we're not quite that far along yet :)

After doing a lot of reading, I have decided to begin work on the server side
of things. My plan is to implement the server the first time around the quick,
dirty and SLOW way, using the mfb and mi stuff. The UNIXpc has everything
needed for X: stupid bit plane, keyboard that interrupts on key press AND
release, same for mouse. I am still undecided about where to draw the line as
far as how to split up the video part of the server. Mapping the video RAM into
the server process is not possible. The video memory resides in 4 separate
4kx4 bit dynamic RAMs at $420000. I do not think a hardware mod would be
appropriate in this case. The thought of having to do an lseek and a read or
write for every access is also not very pleasing. Maybe ioctl() to PixBlit
would be fast enough. Hmm.

Can anyone suggest an easy way to force feed an X server for testing?
