That's great from an idealistic tech point of view, but in the real
world, do you really think organisations will toss out all their
IPV4 routers, switches etc and rebuild the whole system just to use
IPV6 ?.

No, they will use IPV6 where there is a good business case and the
rest of the infrastructure will stay at V4 until it's time to upgrade
the whole network, or for very good reasons. It's cost, cost and cost
every time vs real benefit. Network kit vendors will produce edge 
routers with V6 at the wan and both V4 and 6 for the internal networks.

Yes, we know all this, but IPV6 is not necessarily the best solution for
all such network problems.

Being a passionate evangelist doesn't make a belief system true :-)...
