The first one isn't so simple since any code loaded into the browser can access the audio capabilities of the system. It is possible to isolate running instances of plugins, but don't expect anything like Windows' per-application audio settings. Maybe make a proposal to the maintainers of the NS plugin API?

The second one seems doable, but might fall victim to the same problem that Excel has when you tell it to work with "web data": the structure of a page is volatile. That's why RSS is so popular for syndication.

Yeah; this could be a problem. But most things I would use it for would be portions of pages that have a typically concrete structure. It would break, eventually, when the site structure changes but many (if not all) of the pages I would use it on have a rather concrete structure.
