I have no shortage of anecdotes where a non-trivial layer-2 topology at an exchange point has left my router and provider X's router both able to talk to a route server, but unable to talk to each other directly. Since the NEXT_HOP on routes we each learnt from the route server pointed at an address we couldn't talk to, the result was a black hole.

So while your theoretical work might well have substantial merit, its application to the example at hand seems potentially lacking.

I am somewhat intrigued at this network you mention with which people have practical experience that has more nodes than the Internet does, though. That'd be quite a network.
