i believe this is because bgp will not establish a session unless the other
end is directly connected.  hence the reason for ebgp-multihop.  so unless
somebody drops a physical line into your router and configures it, you
shouldn't have a problem.

at least that's the way i understand it.  please correct me if i'm wrong.
