Protecting Console

[Brent L. Bates AAD/TAB MS294 x42854]

    Someone asked me if it was possible to keep a remote user from
displaying graphics on the console.  They want something set up, so
if they are on the console they don't want someone remotely executing
a graphics program, but they do want them to be able to login and vi
files, compile programs, etc.  They are using a Personal Iris (4D/20).
If doable, would the same work for other 4D machines?
