Just have the activating process invoke a method on the activated
service, passing in the unique bus name of the activating process.

Note that well-known bus names (the well-known names used to have the
bus daemon launch a service) are singletons; so if you want two
instances of your app, you'll need some other mechanism to start them
and locate them. Each app has a unique, non-well-known bus name as
well, which you need to tell the host process about.
