Henry,

No, I assumed that most (but NOT all) of the customers who switch
providers would renumber. I can further weaken this assumption
by allowing aggregation above the immediate provider level
(you can do this with CIDR).

That is not so far-fetched assumption. Proxy aggregation is
likely to happen, whether some folks like it or not.

>CIDR only buys us a *little* time..

Remember there is "CIDR movie", but there is also "CIDR book".
You need to consider both...
