[foxboro] X-window login environments

This should be an easy question for the many knowledgable X-windows users
on this list.
We have an ancient system - AW51B, v4.3 - and are just starting up our
first X-windows station (to replace a PW-OE). I have it up and running on a
PC with Windows 98 and Exceed. Now I need to set up security.

The host AW51B serves as the operator station in one process area and the
X-station is the operator console in another area. I would like the
operators in area A to only be able to see graphics in area A, and B
operators only see area B graphics. I have created separate environments
for the two areas, but I don't want to use passwords to prevent access to
the environments (because we could never keep the passwords secure). Is
there a way to have the X-station boot up automatically into an environment
which the host AW is not able to change to? Or do I need to use the same
environment for both areas and disable the graphics that are not needed?
Ideally, I would like to have the PC power up directly into an Exceed
session logged into the area B environment with no way for the operator to
back out to Windows. Eventually, we will have 2 more of these X-stations as
we replace our other PW-OEs.
