"In order to communicate with running applications on the D-Bus, we need a front end CLI application, or we could use a language binding (say python bindings). However, we will choose a CLI application. It is possible to use "dbus-launch", or the "qdbus" command part of Qt4. I will be using qdbus since it demonstrates the point and is faster to use. So, let's launch qdbus, and list the running communications buses."
