Indeed lack of support for 3rd party signers was where I gave up any

As I remember it, there was (or appeared to be) consensus to get ADSP
out there for testing by the entities it might work for, AND
simultaneously work on something for the 3rd party scenarios.

What ever happened to that work? I know there were a couple of drafts,
and Murray added support for one to OpenDKIM...if the 3rd party stuff
is really that important, why isn't anyone using it?

Indeed, I asked this question at a couple of industry trade groups I attend, 
MAAWG being one of them.  The answer I generally get is that the key delegation 
already supported by DKIM works just fine, so why do we need some other 
mechanism that hits the DNS yet again and employs some complex policy 
expression language?

There has been no uptake at all in OpenDKIM for ATPS, and almost none is 
apparent with ADSP, although in the latter case our data can only give a range 
for adoption because we don't query when an author signature passes.  I could 
tighten that down by running five figures worth of TXT queries if we really 
feel the need to be more accurate.

I don't know of any public implementations of the other schemes.
