Hi Mark,
I followed the HbbTV activities in last years since we are HbbTV member. To make it more clear the HbbTV 2.0 supports launch HbbTV Brodcast independent applications on the TV and not any kind of web applications ( e.g. by using presentation URL). To support presentation API on TVs many HbbTV 2.0 components could be reused.

Second-screen WG (& Webscreens CG),
I wanted to make you aware of a recent announcement [1] by the HbbTV 2.0 consortium of a proposed specification for discovery and control of Smart TVs [2] that would allow "companion devices" (e.g., browsers) to launch a Web application on the TV using DIAL [3].
The relevant discussion can be found in Section 14 of the specification, "Companion Screens," which I have yet to digest fully.
If this specification is adopted by manufacturers, it would mean that a large number of endpoints would become compatible in principle with many aspects of the Presentation API. We should keep this in mind as we develop the Presentation API specification.
