So you favor a natural T-date then?

May I remind you that there is no such thing as a "natural transition"
to IPv6.

IPv6 itself was developed as an answer to the expected runout of IPv4.
It did not arise as a natural and logical progression to the TCP/IP
protocol but rather as a response to a single mistake in an assumption
to the protocol design.

For all we know in another 20 years there will be another fundamental
flaw discovered in IPv6 that will necessitate an "internet Protocol
Next Generation" and we will go through this whole thing all over
again when contemplating an IPv6->IP-NG transition.

Well, DUH!  Since there is no "artificial T-date" as you put it that
everyone agrees on, people do not feel any pressure to discuss a
post-IPv4 world.

Most people are probably thinking that in the absense of an "artificial
T date" that after IPv4 ruout "I'll just be able to buy what IPv4 I need
off Ebay"

Until a timeline is determined for IPv4 there will be little effort
to encourage and market IPv6.

How do you market something that the need of which hasn't even been

It is like trying to sell a bio-diesel car based on the idea that
"one day the oil will run out and biodiesel will be the only thing
you can use as a fuel"

Well sure, you will get a few people to buy it.  But most aren't going
to pay attention.
