What's really needed is a routing slot market (was: Using IPv6 withprefixes shorter than a /64 on a LAN)

I suspect as we start seeing the CIDR report for IPv6, we'll see that
ASNs are announcing considerably more prefixes than that, in order
to localize traffic better.  I don't think it'll be 300,000 prefixes, but
I'd be willing to bet it'll be more than 100,000--not exactly "earth
shattering improvement".
