[Qgis-user] Any ideas? Splitting polygons to only have one point in each polygon

[magerlin]

I've got a layer with building polygons and another layer with addresses. 

One building can hold several addresses and I want to split the building
polygons so every resulting polygon only holds one address (I can live with
some strange shaped buildings).

I have come a part of the way by creating Voronoi polygons based on the
address points and use clipping but my problem is that Voronoi polygons from
neighbouring buildings may interfere with an actual building if they are to
close:

If I could just limit the Voronoi polygon to stay inside the building
polygon...

Anybodý got an idea on how to solve this?

I am by the way using the SEXTANTE modeller to create my own geoalgorithm
doing this - it is a VERY strong tool and highly recommendable even if it is
still a work in progress!
