I had an interesting discussion with someone from Registration Services at ARIN today.
The big requests for IP space (the 11 organizations that hold 75% of all ARIN issued space) do not come from the server side... They come from the eye-ball ISPs. The only /8 issued by ARIN to an ISP, for example, was issued to a cable ISP.
With this in mind, I don't think there's much to be gained here. Optimizing the utilization of less than 25% of the address space in the face of the consumption rate on the 75% side simply cannot yield a meaningful result. It really is akin to rearranging the deck chairs on the Titanic.
The eyeball ISPs will find it trivial to NAT should they ever need to do so however, something servers cannot do - you are looking at numbers, not operational considerations. --Patrick
