We also took a look at dbus. But we decided that we dont need any of the
advanced features of dbus.

One other important aspect we need in out IPC is that it is fast and can
handle large amounts of data. With dbus everything has to go over a
central server process. Therefore it cannot be as fast as a direct ipc.

The only advantage i see by using dbus is that its easier to marshal
data since you get type safety etc.

And by using named sockets we dont have to link against yet another library.
