So you're expecting something other than a normal DNS cache that
exists now.

Small patch to existing cache.

If you're doing a special purpose cache, why not do a smarter protocol
between the cache and the master server?  As far as the client's
concerned, once you need anything other than a vanilla DNS setup, it's
all new special purpose code anyway.

How would one represent "e-mail may appear from sources appearing in
this whitelist" in an SPF record, with your b-tree proposal?
Popularize the b-tree protocol, then have a way to refer to it
included in SPFv3?
