Is the link become available in the WIKI? We are actually working on adding scene and animation editor into the inkscape. This will make the inkscape become an environment similiar to the Abobe Flash. So far, we have finished some prototype to edit multi page SVG file and some simple animation support.
So far, in the integration is only at the Node and NodeObserver level, therefore, its relationship between inkscape and python VM is quite weak.
However, in order to make it easier to use, we need to bind more and more functions into the python. This will make the binding easier to be broken from version to version. This is why we want to make it into the code base.
The other possibility is not to put the python into the code base directly. Instead, define an binding interface which should be used by any system like ours so that we can develop our stuff outside the code base safely. You can decide to include our stuff or not until the technical issue is clear.
I'll list out a few more details on this in the wiki, so that the reoccurring discussion can be captured.
