BGP routing table entries examined:                              639225
    Prefixes after maximum aggregation (per Origin AS):          248678
    Deaggregation factor:                                          2.57
    Unique aggregates announced (without unneeded subnets):      307752
Total ASes present in the Internet Routing Table:                 56403

As 56,000 AS's all start querying each of the registries (ARIN, RIPE, APnic,
LACNIC, and AfriNic) for all 639,000 objects once a day, to see which dozen of
those got sold yesterday.

Sure, that will work. (And no, the problem isn't the number of http hits
on the registries. 35,840,000,000 hits per day is the easy part...)
