The key words in this sentence are "on demand".  I believe that we've
demonstrated that traffic engineering is a viable and beneficial capability
in large scale IP networks.  I would agree that anyone attempting to
perform traffic engineering with a very small time constant would be
pushing the technology past what is beneficial today.
