	AFAIK, there are only two types of exchanges out there today:

		1. Switched Ethernet and/or FDDI
		2. ATM

	We all know switched ethernet doesn't scale by itself,
	which is why we've gone to switched FDDI.

	And, it's quite possible that we're reaching the end of
	scalability for switched FDDI -- unless, of course, some
	amazing new technolgy comes along and fixes everything in
	one swell foop.
	
	Are the ATM-based NAP's having any problems with scalability
	these days?  How far can they go?

	Personally, I'd also be really curious as to any testing
	that people have done or are doing in terms of other forms
	of NAP fabric.  Will gigabit ethernet save us all?
