I really like this idea, because it'd enable true per-site permissions for hardware access — currently one has to give the browser access to everything and trust its ability to restrict access as needed and keep sites cordoned off from each other. The browser itself would no longer need exceptional privileges (compared to other types of apps) in order to function as a platform.
