Feel free to think of solutions. And what's wrong with a sleeping daemon?

I don't think you get what I need: I need the web UI to be informed. I
need to talk to the web browser. Unfortunately, there's only a limited
number of ways to do this. The only browser-agnostic way to do this is
to basically be a website.. that means running a simple HTTP daemon.
It's not meant to be fancy -- it won't look like any other web site
you've seen, it's just some JSON data passed back and forth as a proxy
between DBus and the Web UI. in the case the network is down and the
Shell has crashed, maybe I'll have an extremely simple web UI hosted
on the same daemon that lets you enable/disable extensions, but that's
it.

The shell does monitor the gsettings key, and reacts to it
accordingly. I will check for updates on a cron job, and probably
throw out a notification if I detect it's been updated. I will make
sure that everything is in sync after startup.
