I need the value as what is considered "near" will be variable by implementation, and because different use cases will need different interpretations of "near".

I was not talking about using the mic to determine if the user is close... I was talking about using the proximity sensor to detect that the use was near, so the Webapp could turn on the mic.

Thanks,
Bryan Sullivan

In the user proximity case the developer may want to know specifically how far the user is, if such is supported by sensors.
>>> What problem is the developer wanting to solve by knowing the precise distance from the user to the device (i.e., in terms of min, max, value VS near/far)? With all due respect, the above is not a use case. A use case would be something like "If the developer knows that the user is X value away, then the developer can do the following things:". No one has presented "the following things" yet, specially as they relate to "min, max, value" VS "near/far" (apart to working out near/far!).
