It would be a shame if NeWS gets canned. It can solve so many
problems that X will eventually face. Dave Rosenthal discussed some of
these issues at the 1990 SUG:


X Frame Buffer assumptions:
	a rectangular array
	square pixels
	32-bit color, RGB Encoded
	15 bit coordinate system
	Read/Write on each pixel
	a pixel is assumed to be visible
	a one-pixel line is assumed visible

Impact:
	X won't look well on HDTV (non-square pixels)
	Solid State (Flat Panel) Screens may have defects and single
		pixels should be small. (e.g. 200 DPI) 
		However - this exceeds the coordinate system of X
	Hardware accelerators will be hard to pipeline or parallelize
		(because pixels are read AND write instead of write only)

Plus the multi-threaded, object oriented light weight dynamically
extensible nature of NeWS, suitability over a WAN, device
independance, as well as the flexibility (Changing the cursor from a
bitmap to a procedure that dynamically changes colors, icons that can
contain any image, scaling and rotation, paths that can be text, fill
areas, holes, outlines, buttons, windows, cursors, etc.)

Heavy sigh...... Some people have a vision. Apparently Sun Marketing doesn't.
Just think what would have happened if the energy that was put into X
was put into NeWS.

If Sun sends out the message that NeWS has no future, then it will
become a self-fulfilling prophecy. :-(

I agree with Frank that the only hope is if Sun gives away the sources
of NeWS for a reasonable price. Maybe free to research institutes and
universities.
