<p><font size="4">1) We cited only one IETF Draft (Wilson, et
al.) among them, because it was the first and only one that
clearly stated its limitation (Section 2. Caveats of Use). More
importantly, it was written by three top APNIC officials. Later
efforts on this topic have not introduced (based on my reading)
any more essence to the topic.</font></p>
<p><font size="4">2) "... I was there for those discussions, and

knowledge of the past, you are uniquely qualified to critique on
our work. However, it would be more expedient for everyone, if
you could first read through at least the Abstract and the
Conclusions of the EzIP IETF Draft, before commenting. This is
because EzIP proposal is based on the same general idea as the
references you cited, but with a slight extra step that produced
a series of surprising results. In particular, we took the
"Caveats" above to our hearts before proceeding. So, please put
such issues behind you while reviewing our work. Thanks,</font></p>

<pre>2) On the other hand, there was a recent APNIC blog that specifically reminded us of a fairly formal request for re-designating the 240/4 netblock back in 2008 (second grey background box). To me, this means whether to change the 240/4 status is not an issue. The question is whether we can identify an application that can maximize its impact.

The walkaway I had from these discussions was that while changing the definition of the address space would allow RIRs to sell more IPv4 address space for a few weeks (such as happened to APNIC when the last /8's were handed out), there were not enough addresses in the identified pools to solve the address shortage. So it was in the end a fool's errand. If you want to have address space to address the current shortage, you need an addressing architecture with more addresses.
I was there for those discussions, and I'm not sure how to put it more simply.
