In my other email, I proposed:  

The request and the connection should be the same thing.   

var mySensor = new Sensor('temperature');   
mySensor.onerror = function (){}
mySensor.onwateva = function (){}   

That way, everything is more integrated. I'm not 100% that the above is right… but I feel the whole design of the API could be more unified. The whole talk of Managers, Connections, etc. in the current spec is overly complicated, IMO. As a dev, I just want too know:  

1. what sensors do you have for me?  
2. how do I access (or instantiate) one?  

Adding the whole language of a "connection" implies that I can "disconnect", etc. For me, it's easier to just think in terms of discardable object references.

Much appreciated.
