Interesting...   it does avoid the transit issue, so it's worth considering to 
some extent.   I'll note that the current west-coast interconnects are not 
exactly lacking traffic  so there may be cases where it may not be advisable 
to peer anyway if adds more traffic to the interconnect.

It becomes very entertaining to scale the above model (although it does
provide an excuse to use nearly every BGP routing feature in IOS. :-)
