Folks should be aware that if you do not assume extreme pressure (which
is what it is taking to get IPv6 deployed), it turns out to be quite
hard to get the deployment incentives and structures for a
map-and-encaps scheme to actually work for Internet-wide deployment. It
does work for a range of special cases.

I think that, 12 years ago, you had the best mouse trap.
Map-encap, where you select a decapsulator (consult the map) and then send a
tunneled packet (encapsulated) does
some cool stuff, but it's a pretty significant change to the network
architecture. Definitely not configuration-free.
I am so painfully aware of this.
