Well, as I have said... having to go to 32 bit AS numbers shows that
we've failed at ASN policy-making and failed at creating a scalable
multihoming solution.
We don't _want_ to have to give out thousands of AS numbers per month
or even a year. We'd (well, I at least :) would rather that that the
endsites had other means to do multihoming which wouldn't require such
global resources.
ASN exhaustion is IMHO just a symptom of the real problem. Enlarging
the ASN space does not cure the disease, just makes it worse.
