I mean that the solution will involve a routing table which has
one of the following two properties:

	1.	Growth in the number of prefixes on the internet is
		not arithmetically tied to growth in the routing table.

	2.	The algorithm or method used is designed in such a way
		that existing hardware could handle a routing table
		supporting any conceivable value of assigned prefixes
		(which I would put somewhere around 1e10).

One possible way to achieve this is the use of an ID/Locator split
in the Interdomain arena.  Thus, since the "global" routing table
would not contain prefixes, it would meet property 1 above.

I can't envision a way that property 2 could be accomplished, but,
I accept that there is no possibility that I can envision all possible
solutions.  My attempt is to state requirements.  I believe that
any true solution will have to meet one of those 2 requirements
or it will suffer from the same problems as the current solution.
You may be able to change the scale at which the problems occur,
but, without one of those 2 solutions, the problems still occur
at some scale.  In reality, solution 2 is a pathological case
of changing the scale, but, involves essentially changing the
scale to "the size of the internet".
