costs of different approaches

 hill to climb around the administration of adding another
 record (its type doesn't matter).  Their issue is that
 forward DNS is under the control of another entity and
 just getting the MX to point to the right  place is
 headache."

 Is this one of the primary reasons MARID failed? The DNS
 management issues of Sender ID and SPF are much more taxing
 (orders of magnitude more frequent updates, little
 possbilities of using the same record for different hosted
 domains etc) than the specs that have been proposed here.

The common, public mantra is that approaches like domainkeys are 
more 'complex' than approaches like spf and sender-id.

I believe this is wrong, for exactly the reason you state.  Path 
registration schemes have simpler software algorithms, but far 
more difficult on-going administration requirements.  So it is a 
trade-off between one-time codewriting versus on-going 
administration effort.
