If you have one eBGP session in your whole network, sure.
However if you have more than one, BGP cannot do the "Prefer the path
with the lowest IGP next-hop metric" thing, as OpenBGPd does not know
metrics from OpenOSPFd. Someone commented that OpenBSD would be able
to do this soon as metrics were added in to the routing code in -
current, but I have not tried this personally and a quick couple of
queries on Google didn't reveal anything other than internal OpenOSPFd
I have however used OpenBGPd and OpenOSPFd with great success on
routers we put at single-homed customer sites for a small business-
only ISP I used to work at. We used BGP communities to put prefixes in
to PF tables, and then shaped and accounted based on that. (Here in NZ
we have a few thousand domestic prefixes, which transit to/from is
often cheaper than transit off-shore).
