I'm not sure about that.
D-Bus is a standard implementation of the freedesktop.org, and it's used
by many desktop applications.
It have been done to permit to all applications to communicate together.

There are few applications that doesn't implement D-Bus, and Brasero is
one of them.
Try it, open d-feet, and you will be able to see that there are very few
application that doesn't publish a D-Bus interface.

In any case, if the Brasero project don't implement a D-Bus interface,
that just mean it will not be used by projects (like mine) or with a very
low priority.
( If I don't make a mistake, and I'm 90% sure, all appearing applets in
GNOME are using D-Bus to centralize in menu all informations. See the
messages applet
