    Is it available now for public use?

Not the Sample Implementation.  You can contact various vendors to
find out what their product plans are.

    How about to X Consortium members?

PEX sponsors have received several preliminary releases.  Consortium
members will see releases later this year.

    When will there be a general release?

1990ish, if things go according to plan.

    What are some useful references to learn more about PEX?

Read the files in doc/extension/PEX (PostScript files in
hardcopy/extensions/PEX) in R4.  Obtain any books/articles
on PHIGS you can find; The programming interface to PEX
will be PHIGS/PHIGS+.

    How compatible will PEX be with X11.

PEX makes no incompatible changes to X11, that I know of.  PEX is a draft
standard of the MIT X Consortium.  It is awaiting proof of concept (expected
to be fulfilled by the Sample Implementation).
