This makes no sense. If the machines have no X libraries, how are you
going to run any X applications on them?

(Or do you mean that your X server boxes have no X client libraries on?
Why do you care; all you need is an X server.)

Further, this breaks as soon as you telnet from A to B and thence to C,
because DISPLAY would get set to something on B, which has no X server
running.

A better thing to do is just to leave DISPLAY alone through all your
telnets and sshes; things will just work then (except that you have to
get X authentication set up properly).
