seems correct you can't use X over ssh as root.
I don't know why but always seemed wrong running X as root.
To be fair, I don't think Gene is trying to run X as root (which would
an X *server*), but just a client. Yes, I agree that running X as root
would be horrible, but I have no difficulty in running an X client as
root, either on the same machine or having logged in as root (by key)
to another machine. But I would be very choosy about which clients I'd
be prepared to run.
