	well... not that it gained any traction atall, but given
	the actual size/complexity of the global interconnect mesh,
	we -could- ease the transition timing by many years with the
	following administrative change.  No tricks, no OS hacks,
	no changes to software anywhere..  just a bit of renumbering...

	recipie:

	the usable IPv4 ranges
	RFC 1918

	Step one:   Invert RFC 1918 to define the global Internets interconnection
		    mesh.
	Step two:   make all other usable IPv4 space "private".

	Serves 2,000,000 million clients w/o changing to a new protocol family.


Enjoy!
