	This looks like your normal good manners to me.. :)

	Wish you would have provided these comments when this draft was
	sent to namedroppers@internic.net or wg-dns@ripe.net or newdom@iiia.net.
	But thanks for looking.  In general your concerns have already been
	expressed by Robert E. in a much more civil fashion.

	Bind - Berkeley Internet Naming Daemon.  Others exist
	but this seems to be the most popular and best supported.

	I can't seem to find Blortania in the ISO country code list.
	Perhaps you can forward me the relevent section.

	What are you blathering about? Would you like an Glossary added?

	In some sense, this is a license test. Objective criteria tend
	to level the playing field.  And to be objective, there do need
	to be periodic checks.

	Glad to hear you use NTP. And where is Blortania again?  And when
	did adding NTP as a criteria for TLD service become a "side subject"?
	Thats is what the document is about.

	Yes mine Furher.  (Where are these places?  On Heir Flemmings

	If they are so bloody desireable, they why not tell people that they
	are?  Or are you in favor of keeping others information poor?

	Thanks for your inputs. Perhaps since 85% of the world has zero
	need for or near term interest in DS3 or 100Mb services that no
	one else should work on these issues or publish documents on problems
	or concerns with these issues.  Your right, perhaps we'd all better 
	wait to address any issue until it affects a majority of the global
	population.

	There is zero attempt to promote this a a BCP. As we all know, not all
	RFCs are standards.  This document is being proposed as Informational.
	It is not current practice.  It is proposing a practice.

	Consider it a design goal for whatever universe your living in.
