But its taken us 20 years to get to this point and even with the IPv4 exhaustion it's still relatively slow to be picked up on by providers in Europe or North America (except for mobile, now). Not to say I wouldn't want SCTP to succeed but IPv6 doesn't exactly spring to mind as a model for the successful adoption of a new internet protocol.
