This is something that would be expected to emerge from the analysis of 
use cases and requirements for open markets of services.

The role of scripting is highlighted in the 2nd paragraph at the start 
of the draft charter:

This illustrates that scripting could be used in several different 
contexts, and your concept of a common runtime for connected devices is 
just one of these if I understand you correctly.
