Hi all,
As Martin Dobias asked me, I updated my code and implemented Spatial
Operator in QgsExpression as NodeFunction.
You can review the code here :
https://github.com/rldhont/Quantum-GIS/tree/6535
This mean that it's possible to create expression for style rule with
spatial operator. I wrote a blog post about it :

I hope these capabilities will interesting QGIS users.
