Yeah. The *best* solution would be to have our own mass-checker. My
GetURI (http://ry.ca/geturi/) could probably be extended for the task
without much work, since it already extracts URIs and is capable of
producing statistics.

Maybe if I wired it to *also* accept a ham directory, it could
cross-check domains in both corpora and list possible FPs.

Yeah. Next version.
