Hello, I have written a plugin that exports searches on dbus (it just
does a PROP_SEARCH_MATCH query on a string and returns a list of title,
artist, album, location) but I don't know how to make it appear on the
"org.gnome.Rhythmbox" bus name.
On the C version I have no problem, it just works (except that
deactivation does not remove it, but it can be fixed).
In order to distribute it easily I want to do a python version, when I
use dbus.service.BusName, I can set any name that is not already
registered, but not org.gnome.Rhythmbox which would be more appropriate.
By the way, the plugin is meant to be used by deskbar, empathy/pidgin
without the need of parsing the xml database, is this approach
acceptable or is it a feature that should be first approved and
developed in-tree ? maybe in order to have a compatible interface with
amarok or other similar software.

PS : Here is the plugin if you have time to investigate
