Which distro are we talking about, when thinking about Solaris, Mac OS X and Windows,
for example? This isn't about Linux only; we need a dbus server everywhere.
Isn't the best way to ensure that we get one, to start one when needed?
Of course on linux we can expect that distros will launch a dbus server before kde,
but a fallback solution is very much necessary for all the other cases.
