You're saying that existing processes (A2, A3, A4) are already started via systemd *and* already communicate on the session bus. So take a look at them and figure out how *they* find the session bus. Then just use the same method. For example, if your system is configured such that the session bus is started through its own service and has a fixed address (i.e. the same on every boot), then you can specify that address through the $DBUS_SESSION_BUS_ADDRESS environment variable, or even pass it directly to the DBus library you're using. -- Mantas Mikulėnas
