I think that is an especially important point.

In thinking about use cases in which service providers (E.g. Cable MSOs,
broadcasters) would want to participate, it's easy to imagine a HN UA
wanting to use non-HN communication to perform control functions on e.g. a
cable set-top box.

Then there are cases like mobile devices that may roam between HN WiFi and
carrier 3G/4G networks. In this context, imo, applications should be able
to continue to operate despite changes to network topography.

In general, it hasn't been clear to me (as a newcomer to the TF) who/what
is responsible for building/hosting the HTML/other user interfaces for the
various UAs under discussion.

For example, if I want to browse for services on my HN using a UA on my
mobile phone, does the discovery protocol point my device's browser to a
HN device that is hosting a particular HTML implementation of a service
user interface?

Please feel free to point me in a different direction if this is way off
base.
