        "The trouble with all of this is that the video
	bandwidth required to do any of this is cosmic. No problem
	generating it (well, maybe no problem) but displaying it is
	quite another matter. Building a monitor that can swing the
	beam fast enough to do 1000 lines/frame is a trick only a
	few vendors have managed. 300 lines/inch resolution will
	require 3000 lines/frame. Ouch. In addition, the beam is
	going to have to be modulated at about 250 MHz. The only way
	to do this will be to up voltages/currents in the amp
	circuit and increase the anode voltage- don't sit in front
	of this tube if you ever want to procreate."

One answer seems to me to have multiple guns on one
tube.  Why not divide the screen into nine squares and drive
one high-res gun for each?  I realize adjusting all the edge
convergences could be a slight problem, but I don't see why
it shouldn't be within the state of the art.
