	Very good summary of the situation. But would it be "worth it" to even
	bother with two orders of magnitude ? DNS scales as well as it does, in
	its current implementation, because it's hierarchical (as you point out
	yourself). Technical considerations aside, I tend to agree that having
	an unlimited number of TLDs *in the current state of things* certainly
	wouldn't be ideal.  Now, I don't want to go into a "what-if" discussion,
	but one could imagine other mechanisms, such as peer-to-peer resolution,
	where DNS wasn't centralized, with no real root to speak of (or, rather,
	a "core" of trusted servers with a first-come first-serve registration
	model).  Unlikely, but the mental exercise is interesting, if only to
	try and see where this push for more TLDs will eventually lead.
