while i am not claiming the bgp sky is not falling, we actually have no
good measurements or experiments to substantiate the arguments that we
have a particularly low ceiling.

my guess is that, with current routers, it is the multi-homed enterprise
edge that is likely to hit any wall before the big isps.  the latter may
just see an increase in the rate of needing to appease their line card
addiction.  wuzza wuzza.
