DKIM has extensive design details that are based on using domain names and on 
doing a query to a domain name server.  These details are integrated rather 
tightly throughout the specification.  That said, DKIM provides for specifying 
an alternate key server service.

Let's try to move away from concept and into concrete details.

What specific changes to DKIM are you proposing?  

What is the near-term requirement for it?  

     Absent a near-term requirement, we are faced with comparing the details of 
the current DKIM specification that respond to immediate, known requirements, 
versus hypothetical, longer-term requirements.  On the average, IETF protocol 
specification work that gives priority to theoretical, future requirements, 
over 
concrete, near-term requirements, do not fare well.

Where is the specification for the changes?

How do the changes affect the threat analysis or the charter text?
