ECN favors non-conformant endpoints.  Therefore, it won't help you in
the long run if the congestion is on a path which is shared by
multiple customers.  Popular file sharing software will just set the
proper flags to decrease the discard probability, just like Netscape
opened multiple HTTP connections to the same server.
