Re: [sensors] Possibility of cross-domain communication using frequency in periodic reporting mode

Can you explicitly cite where in the spec this behavior is defined. If
 a sensor has a max frequency of 100Hz, or 10ms per measurement, and 
two browsing contexts have created sensor instance objects that both 
request the max frequency, how should a spec define mitigation for 
something that is outside of the browser's control to begin with? Does
 `getUserMedia` have to deliver video frames at different frame rates 
if two contexts have requested the user's video camera?

Can you give a concrete example?

Firefox and Chrome).

Again, a concrete example?
