One solution is to get away from unlimited bandwidth. Once there is a cost associated to having a PC source Nachi or Welchi traffic, customers will learn to be more concerned and educate themselves. The cost doesn't haveto be moneytary. Progressive rate limiting could be used, where traffic gets pinched as the allowed traffic per time slot is consumed.
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.
