Not sure about that. I'll ask Christian Kellner (author of the project).
The issue is that user is able to define if the device is allowed to connect or 
not. And my assumption is that this is the knowledge of the daemon.
So it would have to be started by some udev event that sends dbus-event.
Or maybe the "IDs" of the devices are stored in the Thunderbolt controller (I'm 
not familar with the specs either) and it's done transparently.

Not sure the content of the '/var/log/messages' is useful:
