Actually, the point about one vs many was completely misunderstood by 
the WG (or completely misrepresented by me).  Stay tuned for a 
clarification.

The point was basically -- could we cut down the number of mechanisms 
to configured tunneling, 6to4, Teredo, and XXX.. where XXX would have 
to be picked or defined somehow... or would we need MORE than these 
four.

I think the scenarios themselves, except for enterprise, are quite 
near to completion.  The difficult part, always, has been trying to 
cut down the number of transition mechanisms, or to find a a very low 
number of common mechanisms.

The scenarios could have completed a year or two ago if we accepted
that the total number of transition mechanisms was something like
5-6...
