[Med] I thought that (2) was about the behavior of a mobile terminal that is attached to both cellular and Wi-Fi +  discuss which server to pick. That one is out of scope. The NEW clarification text is meant to call this out explicitly. 

 If that is in-scope then I am fine with the

[Med] This what we tried to illustrate with Figure 1. With the change we discussed together (s/UE/H(ost)), Figure 1 would be:

           (b) Cellular Networks

                           |<===========Do53=========>|
                      ,--,-|,--.                      |
                   ,-'   +--+   `-.               ,--,--,--.
                  ( LAN  |H |     CPE------------+          \
                   `-.   +--+   ,-'            ,'   ISP     `-.
                      `--'--'--'              (                )
                                         +-----+-.          ,-'
                         +--+            |        `--'--'--'
                         |H +------------+
                         +--+

And this companion text: 

   "In the case of cellular networks, connectivity can be
   provided to a host or to a CPE.  Do53 mechanisms used within the
   Local Area Network (LAN) are similar in both fixed and cellular CPE-
   based broadband service offerings."
