FYI, I'm working on it now.  The changes are pretty simple.  I plan for 
the user interface to be two items on the DKIM page, one to turn ARC 
on/off, the other to tell what domain the incoming Authentication-Results 
will have, defaulting to the same one used for DKIM signatures.  ARC uses 
the same signatures as DKIM so it'll use the same keys.

R's,
John
