I don't really understand what you mean - do you mean that 911 won't accept more than X calls from a single VOIP provider, after they proxy the call? Because the limit is humans answering the calls, isn't it? Is that done on a grid too, so operators from multiple regions can handle overload in one area?
Anyway, I would imagine a more likely attack would be on private PBXes. Only terrorists would want to take down 911, which should be resistant to call floods, but a much larger pool of criminals would seek to disable private phone systems.
