If we're trying to do a generic distance sensor then we're missing at least a field to indicate multiple sensors triggering (which is not common on phones, but I believe is the norm on cars — yes, we have to get used to thinking about those too I'm afraid :).

So lets just create a new dom event as I suggested.  Near and far are defined by the UA.  Thoughts?
