Your first 5 words say alot.  This assumes alot, including customers 
that don't switch providers and inject more specific routes (this is
happening already).  You're also assuming that we have a mechanism
for aggregating routes for folks who choose not to (or can't, for
some reason).

CIDR only buys us a *little* time.  Pigs still can't fly :-).
