	perhaps it is worthwhile to try and note the differences btween
	the two reports/presentations.

	OARC did an empirical study - based on snapshots of a given state
	for -ONE- operators architectural design.

	RSST crafted their study more along the lines of a Risk Analysis Tool
	for the root system overall, not just a server instance.

	Both are useful/needed. The second study alluded to a problem that will
	be much more visible in the next nine months, the impact of a much
	larger response size on the ability of nodes to get a response to a
	priming query.  While not a risk per se to the root system, the collateral
	damage to the rest of the Internet is real and should not be lightly 
	dismissed by those who have been waiting patiently for many years to
	see the root zone signed.

	If the WG decided to do anything wrt sending a note to ICANN, it should
	include some text about the known risk and making the changes anyway.
	This is a clearly destabilizing event.
