Close, I think.
Each POP should advertise its nets via standard EBGP.
They could then setup an IBGP mesh internally. The main point of importance
here is that their next-hop's network must be originated by the upstream
provider.
However this is probably a Bad Thing. You'd need to crank on the IBGP
session's timers to account for lossy paths.
I wonder if there's any particular reason why they're not using private AS
numbers with their immediate upstreams and letting _them_ advertise the
networks.
