the /24s of small multihomers is half the routing table (see geoff's data)

This can't possibly be correct. The last figure I read was that there are about 70k /24s. There are about 21k AS numbers out there. This means that by far most of the announcements, including /24s, are the result of lack of CIDR. Either because ISPs have a relatively large number of PA blocks (address conservation) or because of lack of aggregation.
