The man page is magically obscure, _and_ the system behaves as if
the _user_ root _is_ allowed to display. I don't believe I have
all that secure jazz in my setup either, but it worked for me. And I
assure you, I don't have any system named root on my local network.
Mind you, I didn't try logging in to another system as root and
trying to display to the X server in question.
The other solution, setting XAUTHORITY in the root environment to
that of the user that owns the X session, also worked for me.
I've never seen that before - neat.
