PI vs PA Address Space

Allow me to magnify one of Tony Li's comments:

	It's called good "renumbering" technology.  It solves all of these
	problems. 

I agree completely.  Anything that makes it easy to renumber
all the hosts in a given small-i internet into a new prefix,
or better still, a different-size block, solves almost all
of the problems that people talk about on CIDRD.

I am therefore always at a loss to explain why a couple
of fairly vocal IAB members are so stringently opposed to
developing such technology, and moreover actively curse
a technology that can solve 90% of the cases where renumbering
is a problem (small small-i internets moving to new providers
or *** connecting for the first time ***).
