I guess the answer is pretty much not. The amount of interior
routing information in a properly designed backbone is quite
small even if there is no two-layer abstraction. (Now, the
_exterior_ information is aplenty, but OSPF is useless for it
anyway).
If someone proposed simplifying and cleaning up OSPF i'd be
quite for it. Building a protocol allowing to get rid of
iBGP hack would also help :)
