Cool, I respect that attitude.  At least now I know how to deal with you.  
The glass is half empty.

You are the guy that posted about IBGP Nailed Routes.  I love that idea.  I 
understand your love of L3 and your design is great; however, as a service 
provider, you can't always rely on IP.  What about Global Ethernet?  The NY, 
Paris, Tokyo, Seoul, Singapore, Frankfurt, Moscow, Bankok, Sydney, Hong 
Kong, London, Cairo, Los Angeles, Jerusalem, Toronto, Mexico City, Rio (Can 
I manage this one?) Internet Exchange?  MPLS VPLS over Ethernet Anybody?  
Use your nailed routes trick in the middle (MPLS side) and L2 peering 
exchanges in each city.  Only problem with this is complexity.  Do this 
alone or with few partners and you may be able to pull it off completely L2 
without the cost of complexity.  Simple like you said.  Gotta work on the 
reliability part though.  Test.  I'd like to test in Paris, London, 
Jerusalem, and Toronto.  I haven't been to those places yet and I got this 
cool digital camera.  Please don't shoot when you see a Mexican (American) 
who can't speak Spanish.

That will work, but I don't think carrier pigeons are Internet Core unless 
there has been major pigeon development I'm unaware of.  Good question..  1G 
(.z and .ad aggregates), 2.5G (POS), 10G (.az), 20G (.ad), 40G (.ad), beyond 
are more of the realm we are in nowadays huh?  I suppose you can use WDM 
equipment and get an 802.3ad 100G trunk someday, but then again the 
assumption is that single flows would not be more than 10G :-)
