I think Tony's talking about routing protocols, not hardware.

In any case, I too will disagree with Tony, and say that no possible routing
technology can scale as well as some people would like it to. :-)

Reading this, I literally had to cringe and hold my head in my hands.

The *only* way to aggregate *which is useful to the routing* is based on
*actual connectivity* - i.e. the actual ability send packets. Ownership of box
X and box Y is basically irrelevent (although policty routing may use it for
*additional* constraints), from the routing's point of view. If box X and box
Y are connected by a wire - now, that's different.
