... I know the people working on DK and it's safe to say they understand the
issues at least as well as people here do ...

What of William's concerns ...

Such as?

No (optional) header copying, signature not surviving data additions, only
support for retrieving public key and not having it with message so
signature could at least be verified offline when necessary, plus putting
large public key data in dns is questinable (dns is good for small data
parts) as well as use of TXT instead of specialied dns record (though not
being hard core dns guru, last part I could leave with,
  few others of above as well, but not all of it).

I certainly hope so.  The IETF has an excellent track record at 
taking working technology, tidiying up the messy bits, [...]

Is the newly created DKIM really "working technology"?  

Depends how different it is from DK.  DK certainly works.

Or, is DKIM simply created by a committee of Y! and Cisco people (along 
with unknown others) in a closed environment where people will not be 
able to understand the rational or known problems with a design?

I know the people working on DK and it's safe to say they understand the
issues at least as well as people here do.

It is my understanding that the DK patent license is not compatible 
with the GPL ...  I confess that I have not looked into the details of 
the DK license as closely as the MARID protocol license.

Is there some reason you prefer to speculate than to find out?  The license
is hardly a secret. http://antispam.yahoo.com/domainkeys

R's,
