If he was to use multihop EBGP to maintain a full BGP mesh between all of the BGP speakers in his ASN and each POP only announced it's own networks upstream...?
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.
