RE: ISSUE-14: Gathering requirements [System Info & Events]

Dear all,

+1 for Tran's opinion.
I think usage of sensor will be rapidly growing in the various kind of mobile devices(e.g. iPhone). So sensor API for web application should be provided. 
And I believe DAP WG is appropriate place in W3C.

Best regards,
