[ppml] 2005-1:Multi-national Business Enablement

Terry,
	One of us is not understanding the other.  A global corporation,
in my opinion, usually _IS_ an ISP for it's various departments, VPN
users, etc.  Regardless of the number of external ISPs that they peer
with (paid or otherwise), they _ARE_ an ISP themselves.

	Now, for the ones that aren't, they are multiple islands of
connectivity linked by VPNs.  In this case, each island is either going
to be using one or more PA blocks, or, will be multihomed.  In the case
of a multihomed island, they would be an ORG qualifying under my intent
for 2005-1.  In the case of a single-homed island, I believe existing
PA solutions are as adequate as current V4 solutions.

	I'd like to better understand where the disconnect between what I
have said in the past and your expression in the quoted message.  Currently,
from my viewpoint, your comment does not make sense to me as a response
to my statements.

Owen
