	The differences between digitals exchange and MAE-LA seem to be 
	limited to these items:

		Digital is escorted
		MAE-LA is not (things are caged at MAELA)

		Digital has its generator installed
		MAE-LA will have its installed in Dec

		Digital has -48vdc ready
		MAE-LA has exausted its -48vdc capacity and is adding more

		Digital has its gigaswitch installed
		MAE-LA has not, since there is not yet a demand 

	In other ways, they are functionally identical.

		Both have multicarrier access
		Both support public and private interconnections
		Both support commercial access
		Both havee colocation services
		Both have UPS,preaction fire, cooling, the whole environmental pkg

	Oops. forgot these:

		Digital has a large marketing budget
		MAE-LA does not

		Digital is 20-25% more expensive
		MAE-LA is  based on cost recovery

	Note that MAE-LA, like MAE-West, is not an MFS only activity.
	They have thier own rates, the other players have theirs.
