Two more observations: One is the assumption that mail from subdomains

I don't see any reason for this to be true. I have one opinion about
mail from foo(_at_)aol(_dot_)com, and a rather lower opinion of mail from
foo(_at_)327cb72e(_dot_)ipt(_dot_)aol(_dot_)com, without needing any help
from ADSP.
OTOH, the converse is likely to be relevant to quite a lot of domains,
even if it does not apply to aol.com.
The other is that if you're so desperate to provide complete ADSP
coverage of subdomains, you can do it right now with a specialized DNS
server that does the equivalent of synthesizing names from
_adsp._domainkey.*.example.com. This is no worse a hack than the
sorta kinda approaches, but unlike all of them, it would actually
work.
Yes, that look interesting. But presumably it is more or less equivalent
to doing the full tree walk and then cacheing the result (being careful to
observe TTL).
