> There is a reason there is no "shared bus" in Internet communications.

Yes, but dbus isn't _for_ Internet communications. It was designed to wire together the multiple processes that act more-or-less as a whole to implement a desktop environment.

"Better" is contextual. The main problems dbus solves aren't "IPC" at all - they are things like lifecycle tracking, service discovery, and getting events across the system/user-session security boundary.

dbus-broker looks interesting!
