Laurent,
I'm developping a medical application for surgery planning where i need a volume mesh for the simulation of the tissues biomechanical deformations ..
I'm still new to CGAL, However, I'll think about contributions once i managed to get around more efficiently.

Benjamin,
It sounds interesting the code you did , thanks for sharing it !
