Maybe the real issue is that system-wide services ought to be offered on the system bus rather than the session bus.
For example which process provides org.openmoko.Dialer? If the answer is the X dialer application, then this service is not available when X is not running. But if gsmd is running, then the phone should be able to make phone calls regardless which kind of GUI front-end is in use. So it seems to me that gsmd should provide the service, on the system bus. gpsd would be like that too, I would think. (But I was planning to investigate the gpsd support for dbus next.) But there are potentially permission problems right? How does a non-privileged-user app interact with services on the system bus? (assuming not everything runs as root, eventually) oh well, more general questions I should ask on the dbus list, I guess.
