On a similar note, how about cables for moving a hi-res (HM) monitor about
50'-75' from the computer (in this case, a 3/280 which we would like to
re-locate to a proper computer room from its current home in an
airconditioned lab.)

Also, Roger, please summarize any replies that you receive. We would also
be interested in remote'ing a colour monitor.
