I would say BGP is an exterior gateway protocol and using iBGP as an IGP is unwise. Much like posting to nanog when you have no clue.
Hm. How do your multiple border routers pass routes between themselves, then? Is that not, by definition, an IGP? Simply because it doesn't have to worry about which "random sized network that might or might not move" goes where doesn't exclude the validity of it's IGP status. I don't know of any other protocol that carries BGP data as an IGP (AS Path, MED's etc) in a way suitable for re-export. Moreover, many people do use it as their sole or predominant IGP, particularly where convergance time because of failure isn't an issue and adjacancies don't need to be built using an LSA model (ie, lack of network or administrative complexity).
