I think a different way to ask that question is:  "Does it make sense
for users at the top of the usage curve to share infrastructure with
those in the middle?"  As I noted in the paper I submitted, lots of
networks are built with specific assumptions about how user
traffic can be multiplexed over the shared resources.  It might be
possible to retain those assumptions for a certain period of time
by pushing those who didn't operate in the expected way on to
different infrastructure (requiring that they buy leased-line capacity,
for example); that way the networks' assumptions aren't challenged
by their activity. 

In case it is not obvious, I think that this does not solve the problem,
as the current high-end users are likely just  a few years ahead
of the typical consumer; I think we have to re-think the base
usage assumptions to get anywhere in the long term.
