NeWs is an extensible window manager, you can define whatever protocol
you like to a window by downloading code to the window manager (in Postscript).
NeWS runs a postscript interpreter and uses multiple "light-wieght"
tasks (processes) and message passing internally.

  This is why NeWS might be called a "superset" of X. How one would upgrade
an X-system to NeWS is unclear.

X is very painful to use over slower communications lines. NeWS has internally
been ported to an Atari-ST and has reasonable performance over a 9600 baud
line. What struck me as important about NeWS is that it is based on a high-
level imaging model. It is not just a windowing package. Personally i find
X to be rather massive and inelegant.

  All this is from a talk Gosling (yes the same one as emacs) gave
at UCSC last fall. Last i heard it was coming out in march. US$1000
to universities including source. Apparently sun wants to make the
protocols public and have "reasonable" licensing aggreements.
