Hi Tom,thanks for answering to the second question I made. Please see my comments below.

As the person who presented the authenticator interaction proposal at the meeting I'd better answer this. At the meeting I heard Glen mutter "funny, there seemed to be interest on the list". That may be where the "definite interest" impression came from.I agree with you, Katrin seems to have suggested it should be part of the architecture work. I suppose we can take the AD's advice on whether we need a separate work item just in case the architectural discussion leads to protocol work.
I guess so.
As for external SDOs, Simon Mizukovsky (hope I spelled that right) stated quite firmly at the meeting that other SDOs have already specified protocols in this area. I myself am unaware of such work (though 3GPP and 3GPP2 may have done the logical equivalent), but it seems reasonable to allow for its existence. One interesting point: Simon said the solutions were technology-specific. That suggests that there is work needed to develop a cross-technology optimization.As the charts themselves indicate, that could be based on 802.21 signalling. If so, the protocol work obviously belongs to 802.21. However, are there scenarios where an IP-based inter-authenticator protocol would be useful?I seemed to have reached a conclusion that we'd better do the architectural work first to find out.
I also agree with your conclusion. Best regards.

On the other hand, there was definite interest in this topic on theSecondly, I have just checked the e-mails in the ML but I failed to see the interest as a work item. In fact, the only thing I have seen is one comment in this e-mail:list before the meeting.http://www.ietf.org/mail-archive/web/hokey/current/msg01623.htmlwhere it is said that this should not be a separate work item (If I correctly understood).Am I missing something? Could you point me the e-mails I missed about this interest?Btw, the charter text says:"Related work in external SDOs on authenticator interaction for re-authentication may be taken into consideration."I would be interested in the related work in external SDOs, could you point out some references?.If they are still valid, then I don't completely understand the general purpose/goal of this particular aspect. What are we trying to solve here?.As to the second question: one would have to look at the scenarios on theslides, but I think they are still valid.Best Regards.
