Sorry that I bombard this list with probably not so useful messages, 
just cannot resist :)

XParts may be considered as "out-of-process KParts" that are accessible 
via DCOP. So KXPartsHost is inevitable for cross-toolkit embedding. The 
big picture updated:

1. Create DBus.Embed - a set of interfaces for embeddable GUI controls, 
containers and an activation server
2. Create DBus bridges for CORBA, DCOP and UNO to access Bonobo, XParts 
(and hence KParts) and OpenOffice controls via DBus
3. Since XPCOM does not support remote objects, create DBus binding for 
XPCOM to access Mozilla controls
4. Create plugins for DBus.Embed activation server that will be 
translating requests between incompatible controls and containers 
("dynamic" proxies)

This is just a raw idea.
