Can either of you provide estimates of how densely these blocks
are populated? What percentage of the individual host addresses
are currently used by functioning hosts (or router interfaces)?

Of course -both- of these ISP's are running RWhois servers which
accuratly reflect the delegations that they have made and which
can be used to document to the Internic that they need more space.

(beats SWIP entries all hollow IMHO)
