Yes, I've thought this a bit. Some questions to all:

* First, does someone have concerns with adding support for intensity (API design details aside) to the spec?

* Type of double scaled from 0 to 1.0 or type of DOMString low|medium|high or something else? I'd like to note that implementations should obey the platform level vibration intensity setting. For example, when a "meeting" or similar profile is selected, the device is typically set to vibrate only slightly, and in such a case 1.0 or "high" would represent the maximum platform capped (e.g. profile setting) intensity.

* Is everyone fine with overloading vibrate() with intensity, or should we carve this functionality out into its own method?

Deepanshu - Thanks for the proposal!
