Well, I think I'll try to copy the appropriate part of the mesh, move it 
(very) slightly and try to map the image on it - like your description on 
your website, so that the mesh itself is completely transparent. I hope 
that there are no edges visible when I prevent the object to cast shadows.

Thanks so far,
