I believe you use /dev/right to find the ethernet id for the machine to
your right, but to get the ethernet id for the machine on the left, you
need the new GNU addon device driver /dev/ambidextrous.  Implementation of
these devices is hemisphere dependent, the default is for the northern
hemisphere (except of course for the UK, since there internet addresses are
backwards).
