Josh and I are not asking about FAST.
We're asking about whether GSS-API is the right layer for this.
To me this is the big open question in whether I personally thing this
draft should be advanced and any discussion you can provide of the
issues I brought up buth in general and with regard to the use case of a
service wanting to obtain a service ticket regardless of client support
would be valuable in making my own determination about this draft.
