I don't buy it for a millisecond. Why in the world do people think that all ISPs are going to migrate to IPv6 in lock step when the evidence overwhelmingly contradicts that? For that matter, why do people assume that all users use the same applications and have the same needs, or that all applications have 'clients' and 'servers'? > To whatever extent the ISPs lead the servers, however, > you are ultimately going to have to rely on NAT. NATs will have to be used in corner cases.
