Live example of how well monetary pinching works in New Zealand --
there have been cases of people receiving $15,000 monthly phone bills
which are mainly comprised of ADSL traffic charges. So, the traffic
charges stop the rogue traffic, by sending customers bankrupt, but only
about a month or so after the fact.
Punishing high-traffic users by progressive traffic shaping sounds more
effective, although the implementation sounds potentially hairy.
