         (Or "Infobahn", "Info Strada") The name
        coined by US Vice-president Al Gore in the early 1990s for the
        emerging high-speed global communications network capable of
        carrying voice, data, video, and other services around the
        world.  These services use satellite, copper cable, {optical
        fibre}, {cellular telecommunications}, and are accessible via
