Geoff,

"Of the 32,557 assigned AS numbers, some 19,859 are advertised, while
12,698 have been allocated in the past, but are not currently advertised
in the BGP routing table."

I would have liked to see how well the RIRs are at recovering unused
ASNs, if at all.  For example ARIN has a 30 day policy:
http://www.arin.net/registration/templates/asn-request.txt

Do the RIRs *ever* revoke an ASN after the customer does not follow the
RIR stated rules?  Would love to see numbers on that issue.  No wonder the
ASN pool will expire in 2010.
