Ken,
Technically speaking, even eBGP has the ability to peer with
neighbors that aren't directly connected. Typically, eBGP peers will have
diect physical connectivity, whereas iBGP peers are part of the same AS, as
long as a route/path exist to that peer, connectivity shouldn't be a
problem.
When you address this issue, think of the requirement for BGP to be sync'd
with the IGP for route information to be advertised. As well as the
limitations/features of the peering relationship from one AS to another, or
devices within the same AS.
