Mechanisms have existed for like 20 years before dbus to communicate

better".
That's why I dislike it.
I'll preface this by right up front saying that my knowledge of dbus is
actually pretty limited. So forgive me if I'm off-base in my comments.
But frankly, I didn't think the *intent* behind dbus was as a
replacement for IPC. As I understood it, dbus was intended to be a
system-wide message bus - i.e., a very generic pub/sub type of system
that could be used by any component in the system. Some components
would publish messages of a particular, and other components would get
notified about messages of a type they're interested in and react to them.
Makes some sense to me to do things this way, as then you can just have
a single, standard system-wide daemon that every app interacts with in
the same way, rather than force each app to reinvent the wheel and
implement their own solution.
