Michael,
Thanks for brining these issues to the DT. I would like to add few more 
points.

Thanks,
-Subir

              where AP/AC belongs. Also AP/AC can not be used as a 
bridge.  So the model is:

                         L2                                   L3+
     STA  <-------------->AP/AC <------------------->IS Server

Subir> This is one of the options. These problems will not exist if  
AP/AC implements some of the
            MIH functionalities similar to 802.16g. If it uses L2 
between STA and AP/AC,  how the
            response will be send is an implementation issue. On the 
other hand, the important point
            is:  do we support the above model whereby the intermediary 
is not an MIHF but
            communicating with the IS server with a L3+ transport protocol?
