Indeed.

The reverse is true on the Web side of things -- "starting 
programmatically the capture without a specific interaction from the user" 
is something we'd never want to allow on the Web (consider how porn sites 
would be a very different experience if they took video of you while you 
visited the site...).

This is probably an example of a set of requirements where we actually 
want two specs, one for widgets and one for the Web.
