	Its pretty big.  Most of the data is not verifiable, but
	a profile of 100-10,000 subnets, between 5-2000 nodes per subnet
	w/ RIPv1 seems to be emerging for sites like Xerox as well
	as old NSFnet regionals.

	On the other hand, reports of large, multinational networks
	running static routing in their cores seem to indicate a
	desire to have routing in the core more stable than any dynamic
	protocol will allow.  

	With the growth in the number of injected prefixes and varient
	paths, one might say that the "value proposition" of dynamic
	routing is not what it once was... Or it could be that the
	folks running the big networks are more comfortable with 
	manual/static routing systems?  Such environments certainly
	provide easier means to set enforcable service level agreements.
	But my muse has gotten the better of me.
