Also, what happens if it rains? Most 'weather sealed' lenses and bodies go to great pains to put O-rings on everything and completely separate air inside the camera from air outside. I imagine that's a lot harder to do with this design. Given that lens fungus seems to be caused by humid air, isn't there a risk that this design will effectively decrease the storage life of it in real-world conditions?
