help converting a scene in Mitsuba Render

Dear All,
In order to perform some test on different renders and to create a test scene @ cgsociety we launched the Lighting Challenge #44. You can find the thread here http://forums.cgsociety.org/showthread.php?p=8223693#post8223693.
I’m searching for someone that can export the scene in blender and in mitsuba format (so we can compare the different engines). Can anyone help ?
thanks in advance
G.
