Well, between that, and, the fact that ISPs should be asking for additional
space a _LOT_ less frequently and all cases should be more likely to
get an aggregable expansion of their allocation/assignment now that
we are delegating by bisection, I think both of those things will reduce
the rate at which growth within organizations increases the routing
table by quite a bit.
