i rant, yet again.  

	what is this "the" public routing table?  where does one
	get it?  in my 25 years of networking I have NEVER seen it.
	i am convinced that it is a fictional as the "public" Internet.

	than the H5N1 strain.  Note that it affects normally sane engineers
	who KNOW better.

	back in the SRInic days, there was the "connected" and "unconnected"
	databases.  ... to mark prefixes that were connected to the ARPAnet
	and those that were in "private" networks, like CSnet, NSFnet, and
	enterprise networks.  Tony is right in this respect, RFC1918 space
	is a feeble attempt to get around/past the lack of address space
	that became apparent in IPv4 ... with IPv6, there is no real 
	reason to try and recreate private space (leaving aside renumbering)

	IMHO, assigning globally unique prefixes to those who utilize IP
	protocols, regardsless of whom else they choose to "see" via routing
	is the right course.  every other attempt to split the assignements
	into "us" vs. "them" has had less than satisfactory results.

	I am unconvinced that it can be made to work successfully in the
