there is a small niche set of examples of this, the university occupying 
part of a building and having their own response personel is one example, 
but the most compelling one is when a government agency occupies part of a 
building with their own repsonse personel. This is actually crossing not a 
desired, but a necessary jurisdicational boundary.

But, this will not happen very often.

Also, I'd like to think that all devices within that federal agency talk to 
their own service when calling for an emergency first. This will be a 
function of the configuration of the VVoIP network within that agency's 
devices, I should think, and not necessarily something the general public's 
DHCP protocol should have to account for.

we're getting a bit away from the 80/20 rule and towards the
99.99999999/0.00000001 rule with the later number dictating some of our 
directions/positions
