Dave,
Wasn't the comment made at the mike focused on having the class E
address space be used between the two layers of NAT?
Regards,
Brian

It's been pointed out several times in the past regarding class E
space that you cannot expect a host/app to work if you try to give
it a class E address.
So class E addresses can only be safely used in networks for which
you have complete control/confidence over all the devices/apps
in that network.
It might be usable between routers in an ISP.
It is not really usable to assign a general-purpose PC acting as a CPE.

After the presentation on the intarea session yesterday I though about
something that was said ( I do not remember the person that did the
comment) in the last NANOG meeting during the panel: " What Would Jon
have Done About the Addressing Challenges Currently Facing Us?".
The comment was about what Jon Postel did with the cable companies and
the 24/8 network. He allocated the address block but forced the cable
companies to test CIDR. In that sense he gave something and got
something.
I wonder if we could take that example for the "shared address" case
and re-activate the re-definition of the Class E space as "for private
use" (draft-wilson-class-e-02) in order to be able to be use for this
architectures if the ISP are willing to do so.
