There's a long-standing TODO item to implement that in conjunction with
gnome-dvb-daemon.

That feels hackish.

I don't get that part.

Usage examples for what? "external" is a DBus consumer, you have to
implement a DBus spec, http://live.gnome.org/Rygel/MediaServer2Spec to
interface with this plugin. Knowm implementors currently are
gnome-dvb-daemon & grilo-rygel.

For gst-launch examples are in the default configuration file.

I don't get the part with the shell script.
