Does any end network capable of justifying a /24 then get a routable chunk, thus blowing up the tables? What if you could do it based upon traffic generation? That would be difficult to verify, and the definition for 'large' amounts of traffic is ever changing. So, if we say that a /20 is a sufficiently large amount of space to get a routable chunk, then they would be able to get it from ARIN anyway, and we're back to square one. In the far term as space becomes scarce we will need to find a solution to wasted B space, but that is several years out. Perhaps by that time routers will have so much memory and CPU as to make an extra ~4 million possible routes negligible. Austin
