Back in the day, the folks who ran the RIRs (at the time) were a bit distressed at that IAB statement as we had seen the writing on the wall and were telling customers that due to the limited nature of IPv4, if you didn't want to connect to the Internet, you should use private addressing.  It was a bit of a "War of RFCs" (1597, 1627, 1814, 1918).

	this is my take as well.   The RIR system works quite well, esp for 
	networks/networking based on the previous centuries interconnection
	models.  Its the best method for managing constrained resources, such 
	as IPv4.

	something like ULA, esp the -C varient might be worthwhile as an alternative
	distribution channel, a way for folks who want to do novel things with 
	networking/addressing that are not comprended in the normal bottom-up
	processes of the RIR system.  In your words, "avoid the adminisrative/cost
	overhead with entering(maintaining) a relationship with the RIRs"

	I see this proposal as a vector for inovative change.
