just as Informational or Experimental.  they can't standardize them 
without a Last Call.  even so a Last Call would still be advisable.

all of the authentication schemes I've seen suffer from one or both of 
these problems:

-  trying to do more than is reasonable for that particular approach
-  trying to retroactively change how the mail protocol is used, or to 
restrict future use of the mail protocol such that valid use cases will 
no longer work

what we really need is a framework that allows multiple schemes to 
coexist and work constructively together.  but that can't happen as 
long as the schemes try to change the mail protocol in incompatible 
ways.
