Yup, I'm working on it.  My current plans are for a draft with two co-authors 
that spells out ~4 different ways to accomplish the authentication without 
touching IKE.  Each will be spelled out in enough detail to make it obvious 
how to do it, and what the costs and benefits are.  We'll take whichever the 
WG likes (if any) and turn it into a full-fledged spec.
