RE: web intents version of sensor api

As Bryan implied, it can be seen as 2 separate problems.  A very simple API for common device sensors (where we know what they are).  A Web Intents solution to comprehend local network or farther afield sensors.

In response to a previous email.  I think  the back and forth has been useful.  It seems fairly clear web intents for these device sensors is not what the WG wants.  The question is whether it is one direct api spec (without discovery) or 7 similar ones.  I think that's progress/
