Hi Anant and all

I am not sure how the resources behave when busy, but I often use
chrome to test webrtc service, I often in 1 tab open a page then the
page gets stream from the camera, and in another tab i open another
page I can also get stream from the second page.

And i think it will be common the same camera will be shared by
different page in browser, as I always do in webrtc demo development.

So I suggest we do not specify that second call to camera will counter
"busy",but may promote to user that the resources currently used by
which application, which has more practical meanings.

Hi Group,

I have added a new non-normative section titled "Implementation
Suggestions". The first two pieces of content that the section includes
are two issued that we brought up at the last telco. I hope we will add
more content such as UI guidelines for browsers, and expected usage
patterns for getUserMedia in the future.

- Resource reservation: how devices are generally expected to be
reserved, and recommending that the user be allowed to terminate running
sessions in favor of providing a stream to the current page.

- Multiple streams: Suggesting that multiple calls to getUserMedia from
the same page be allowed and handled in a sane manner in order to allow
the page to get independent video or audio streams.

Please review the latest draft at
http://dev.w3.org/2011/webrtc/editor/getusermedia.html (section 3.5)
send your feedback to the list!
