I agree with Jukka. Working to a lower level of binding (through GDAL/OGR) would let other foss software leavarage the improvements. I don't know Inkscape very much, but I've tried to import the latter example from Jukka (the multilayer PDF) and it keeps the layers correctly. Working on the GDAL level is probably harder then doing the work on the Python level directly between Qgis and Inkscape, but I feel it would be far most used and useful to improve the GDAL PDF support...
