Try muxing the outputs from 1000 framebuffers into a single analog stream.
I would rather pass on this approach.  The PixelFlow box captures the output 
from a composition network rated at 4 Gbytes/s into a single frambeubffer.

I don't believe this approach is truly scalable either, since its still
an example of the N to 1 mux problem.  So it is, in my opinion, contention
limited (the laws of physics won't cooperate and provide infinite digital
bus or network bandwidth).

I advocate a tessellated display approach myself, where each tessellation
element owns a processor, framebuffer, and display.  The trick is to coordinate
the system temporally.  The scalable concurrent visualization system trades
contention for asynchronous execution.
