I personally haven't taken much interest in PCP because I expect large
scale CGN and DS-Lite to be fairly shortlived, but at this point I
really wonder how ISPs are intending to deal with malicious
denial-of-service and/or customers starting e.g. BitTorrent clients
that need 750 connections each (number according to Alain
Fiocco/Cisco, at the German IPv6 Summit two weeks ago).

But then, basically the same issue applies to CGN in general.


Cheers,
