Do you really need the actual video display  signal?  Why don't you just
read the contents of the frame buffer  across the network?  You could do
this with a very simple Starbase program using "block_read".

Any  video  based  solution  is  going  to  require  video-out  hardware
installed in every workstation you want to snoop.
