This is news to me. I always assumed that the amount of data one could
pull around a network was constrained by the physical limitations of the
cable/fiber, not by some standard that decreed what the max bits/second

If there's really "unused" space on any given network, wouldn't this be the
first place hackers and providers would work on to get more bits in and out
of a system?
