The increasingly ubiquitous availability of broadband, together with
flat-rate pricing, have made the use of new kinds of peer-to-peer
applications increasingly common.  From the perspective of the
Internet's evolution and its contributions to end user value, this is
very exciting.  However, the uptick in peer-to-peer application usage
has also contributed to the rise of "high-consuming users" who take
their flat-rate contracts to the limit by continuously file-sharing
to the maximum extent possible.  Network operators have responded to
this phenomenon in a number of different fashions.

This document discusses the problems created for operators by high-
consuming users and illustrates a number of techniques operators are
currently using to cope with high bandwidth usage.
