This RIPE-like scheme is an extremely good one, and it would be a fantastic idea for ARIN to continue evolving towards an allocation policy very much like this.
ARIN already allocates addresses this way, although not quite as aggressively as Karl suggests. Basically, if you have utilized your last allocation efficiently within the 3 months your next block will be doubled up to a /14. In many cases, we allocate addresses from larger reserved blocks which also addresses the problem. So, in many cases, ARIN's allocation procedures are even more aggressive than RIPE's or Karl's.
