you've got to have colo at the CO. I'm not sure how they're
going to hand off. I would think it would make sense for 
CLEC's to do the aggregation of DSL subscription and point
it back to the customer i.e. the ISP pulls a circuit into 
our CO, and we split the traffic after carrying it back from
the CO for the ISP.

Disclaimer: I'm thinking out loud. We're about to start DSL 
trials and I'm only certain of the colo situation.
