Any transition solution, whether from IPv4 to IPv6 or a successor

new protocols will be operating.
Given the amount of time any Internet-scale transition must/will take,
the term 'transition' is tending to be problematic, because it
encourages of tone of temporariness.
When the scale is one or more decades -- as we seem to be seeing
regularly -- the better model is long-term dual-stack with
interoperability support (gateways and tunnels.)
Further, there will have to be two incentives at work for the transition
to succeed.
+1, but the challenge is figuring out who to incentivize and making sure
the incentives are powerful and real (and usually immediate.) We all
have a tendency to imagine incentives that are convenient to our goals,
whereas those doing the uptake often prove remarkably uncooperative to
our view...
