Just as Allen and I have said in previous postings. Using PEXlib
directly forces the application to deal with implementation specific
issues of the server-side PEX implementation. It also exposes the
application to a non-backwards-compatible PEX protocol revision
(analogous to converting your X10 Xlib-based application to X11). An
API (i.e., not PEXlib) such as phigs hides these protocol issues from
the application.

I'll let someone who is more actively involved in the PEX effort field
this question.
