XParts is an asymmetrical, one-way embedding.

Portland Embedding should be symmetrical (and thus neutral) to all 
parties and avoid hand-coded proxy containers (like KXPartsHost in 
XParts and "special controls" in my first guess: 
http://lists.freedesktop.org/archives/portland/2006-May/000435.html).

A new DBus-based embedding may serve now as a bridge between existing 
incompatible embedding technologies...

...but evolve into something bigger in the future (e.g. exposing plain 
widgets for embedding automatically by means of introspection)
