Yeah, bus1 is something very different as I see it. It's not really a
successor to D-Bus, and there's no intention to "port" dbus onto bus1
or anything like that. It's more another player in the world of IPC
plurality, that's all.

This would be purely a reimplementation of dbus-daemon, and use

I don't think this is going to happen. bus1 is one thing, and dbus
another. dbus is going to stay around, but we'll hopefully replace
its implementation in dbus-daemon by a newer one.
