John,
we can discuss it for the very reason you pointed out, people want to use/sell 
3rd party signing, so lets discuss a policy and write it up. I know my company 
wants one and I suspect a few others might as well.  I know that some folks 
fought very hard to keep it out originally but as I pointed out then, its time 
will come

Since there's no such thing as a "3rd party signing policy" in DKIM or 
ADSP, I don't understand why we're even discussing this.

R's,

Since anyone can generate a DKIM signature with a signing domain they
control, an unconstrained 3rd party signing policy means precisely
nothing. Without some kind of constraint (1st party only or a defined
set
of third party signers) arbitrary senders could meet the policy
requirements.

- 1.

Make that a -2 for all the reasons Scott indicated.
