It's on the system bus, so there's no danger of the client (data
engine) and the service ending up on different session buses.

The D-bus security policy for the service does deny access to all
users except those at the local console (at_console="true" in the
config file) or those of a certain user group. That's intentional. But
in my case, my user account meets both criteria.

This may very well be a D-Bus bug/feature. Maybe it always denies
access to processes that were created before a new service is
configured. But I have to work around it somehow or communicate to
users that they have to restart in order to get things to work.
Obviously, I'd like to avoid bothering the user over this.
