Yes, a technology for toolkit-independent embedding of GUI controls, but 
not a component model.

I just found D-BUS and it looks to me like a unified communication 
mechanism between different object systems. D-BUS (if I got it right) 
may be considered as a bridge between objects written in binary 
incompatible languages/toolkits. So that you can invoke a method of a Qt 
object from a GTK+/C# application for example.

Q6: Is D-BUS a "component system"?
http://dbus.freedesktop.org/doc/dbus-faq.html#components

Implementing XEmbed-based GUI control embedding via D-BUS (DBus.Embed ?) 
probably could be a first step to KParts/Bonobo interoperability. I am 
new to these topics and can only guess what may be done next:
1. Create special KPart and Bonobo controls that will act as containers 
in DBus.Embed environment
2. Extend KParts and Bonobo systems to expose their controls to DBus.Embed
