I agree with you. It is painful to program in PHIGS. Of course,
Programming in X is a pain if you use X lib, but it is easier to
program using Toolkit than using X lib directly. I think good
programming tools in graphics, like X Toolkit, would make your
programming easier. Such a utility, let's call it "PEX Toolkit", 
would provide the basic functionality necessery to build a variety of
application environments.

Anyway, I wanted to know if the concept of PEX, which means the PEX
protocol, would be popular.

If the communication between a client process and X server process
through a network becomes much faster, the client process, which may
run on a graphics server computer, makes graphics images and sends the
image data to the server process without using the PEX protocol.
