	Oh, guys, it seems to me that most of the better part of the
	world is surely ready to switch to native IPv6.

	However, what about the locations as distant as 83° E 53° W?
	There, I'm a customer of an ISP that offers a NAT-based service,
	so I, and their other customers, have no (Internet-routable)
	IPv4 address, let alone IPv6.  Thanks to the brave old RFC 1918!

	Or, actually, they began to offer static Internet-routable IPv4
	somewhat recently.  Alas, this service is based on NAT, too, so
	neither 6to4, 6in4 or Teredo (unless relayed.)

	With regards to leaving this ISP and looking for another, the
	state of the local market seemed (the last time I've checked it)
	so bitter, that I've chosen to make a deal with an ISP in
	another city instead, connecting to them with OpenVPN.

	With that, and a few IPv4 I now have, I was able to get into
	IPv6, thanks to both HE.net and 6to4.  And my coworkers are in
	the deal, too.

	Now, given the story above, are you sure that the world at large
	is ready for the transition mechanisms to be shut down?
