<div>Hi Doug,</div>
<div><br>
</div>
That's what you wrote. Here's what I read:<br>
<br>
</div>
<div>"We decided keep this mile of road closed because you
can't drive it anywhere unless the toll road operators in
the next 10 miles open their roads too. What's that you say?
Your house is a quarter mile down this road?** La la la I
can't hear you. Look, just use the shiny new road we built
over in the next state instead. Move your house there. The
roads are better."<br>
</div>
<div dir="ltr">
<div><br>
</div>
<div>** Not every unicast use of 240/4 would require broad
adoption of the change. Your reasoning that it does is so
absurd as to merit outright mockery.<br>
</div>
<div><br>
</div>
<div>> So no, there were exactly zero "IPv6 loons"
involved in this decision. <span

<p>So leaving aside how interesting I find the fact that you snipped
the part of my comments that you did, the utter absurdity of your
toll road analogy shows me that I will not be able to convince you
of anything. <br>
</p>
<p>So I'll just say this ... if you think that the advice I received
from all of the many people I spoke to (all of whom are/were a lot
smarter than me on this topic) was wrong, and that putting the
same LOE into IPv6 adoption that it would have taken to make Class
E usable was a better investment because we're not running out of
IPv6 any time soon, then you have a golden opportunity. Go forth
and prove me wrong. Go rally support from all of the people and
companies that you need in order to make any part of Class E
usable for any purpose (even, as you point it, if it's not for
global unicast). If you're right, and I'm wrong, your income
potential is essentially limitless. <br>
</p>
<p>Or, look at it from another perspective. If you're right, then
why, in the last almost 15 years, has no one figured out how to do
it yet? Including the companies whose mission is to sell us new
hardware, and force us into contracts for software upgrades in
order to keep said hardware on the 'net? <br>
</p>
<p>It's easy to sit back in the cheap seats and squawk about how
"they" are out to get you. I'd be far more impressed if you put
your money (or time, or effort) where your mouth is. <br>
