D-Bus is that already today.

I think that Scott and I explained that this would only increase
complexity inside Upstart and that this makes basically no sense. We
don't need support for two IPC mechanism. We use D-Bus.

And if D-Bus looks like such a problem to you, then even Upstart might
not be the right solution for you.
