Ick!

	1. Talk to WCOM for answers.
	2. L2 media segmentation is a "fun" troubleshooting problem
	   Geographic seperation of various media that compose an exchange
	   have led to most of the extended outages. Its even more fun
	   when the various sites are managed by diverse parties.
	3. Depends on your politics and those in whose sandbox you wish
	   to play. Are you willing to subscribe to the same operational
	   policies as the other sites that comprise MAE-EAST?

I'll note in passing that several exchanges, in and out of the US, have
a geographically distributed model. Generally the designs are not based
on clusters of clients wanting to interconnect.
