I don't remember discussion of recording divs (though there may have 
been)... though there has been discussion of recording tabs.

Firefox has a tab-sharing API, but it's not accessible by web apps at 
this time; it was used in the former built-in Hello service. Chrome also 
has one, as chromeMediaSource: tab, but I believe that's only available 
to installed Chrome-only extensions. Generic use (as in Hello - not the 
current tab) requires some API for selecting the tab as well.

There are significant security issues about sharing data that may not be 
visible to the user, and more to the point explaining to them the 
privacy/security impact of this (thus why Chrome is limiting it).
