Hi dave,
Thank you for getting interested!

I introduce two slides*1,*2 from menbers of MozOpenHard community*3 explaining the concept of Pervasive Browsers. The difference between the existing WoT and Pervasive Browsers is expressed by this page*4 and this page*5.

I also prepared the slide*6 which added the concept of pervasive browsers
to the 3rd page of the slide which you produced.

And, we are preparing the specifications considered to be newly needed by
this concept. WebGPIO*7 is that one.

TDL is essentially about linked relationships between things and their events, properties and actions, and relationships to other things.  So from this perspective, it  would be a conceptual mismatch.  HTML5 is well suited to provide a user interface for interacting with things.

The single origin security policy would allow the web page scripts to access things hosted by that server using either HTTP or Web Sockets. A JavaScript library could be used to create objects in the web page’s execution environment that act as proxies for the things hosted by the server. Direct access to things hosted by other servers would be disallowed unless those servers had set an appropriate CORS policy.
