	It is the end customers.  They don't care if the root servers
	are in or outside the country they are currently in provide they
	get a reasonable level of service.  Neither should this draft.

	The only places in the world where the end customer will be saying
	"I want a root server in the country because there is not one" are
	those countries where only way to get reasonable service levels is
	to have one in the country.  I've heard plenty of time "We need
	another root name server in Europe" but very seldom "We need
	another root name server in <pick a European country>".

	I say we need servers in Australia because I know that there is no
	way to provide the service levels needed without physically
	locating the servers in Australia.  But Australia is large and it
	does not have close neighbours.

	Root level service should be measured in milliseconds or 10's of
	milliseconds not 100's or 1000's as it currently is.  A large
	portion of the world gets that service now.  They are not arguing
	for more servers.  The rest of the world is.
