ok, but you are getting my point, right?  the caching-scale issue *on the client
side* is the same regardless of whether the domains exist, are in the DNSBL,
etc., and I don't think we're talking about a cache-scale issue on the *server
side*.

In other words, caching is trivially attackable *right now*, regardless of this
proposal.
