One option would be to Just Do It, just break the company up along that sort of arbitrary line, and expect that that will push the Baby Faces [1] to be forced to communicate with federation protocols, which could also let others in to play too. One would imagine a condition of the breakup would be that any such federation protocol that was developed could not privilege the Baby Faces amoungst each other.

It isn't necessarily the best choice, but it is one choice. I'm not sure there's necessarily a much better one, either. It's a very big problem to try to wrap your head around.

[1]: I think you heard it here first, though I can't promise nobody else has come up with that. I haven't heard it before to my knowledge.
