Maybe not for some people, but I have a hard time understanding why one extra ebgp session is such a novel concept for all you networking folk.

multihop bgp means that you don't have synchronised ethernet carrier status between the provider and customer routers. This in turn means that if there's an intermediate connectivity problem, bgp will need to time out before it notices and reroutes. During this period, traffic will be black-holed. This is a crock.
