Chuck,
Wouldn't it be safer to say that if a BGP speaking router learns a
prefix from a peer that doesn't have an AS-path attribute (what you
referenced as being originated from) then it is IBGP because bgp
won't tag it's own as-path onto a prefix until it tries to go over a
ebgp connectiong. Furthermore, when you set up your 'neighbor x.x.x.x
remote-as yyy' your pretty much defining that routes learned from that
neighbor are ibgp (if that yyy is the same as your yyy) or ebgp (if
they're different).
