Hm, could you post the code for that? Just because I'm curious, my 
solution was different (and IMHO a little more intuitive):

All the objects in question are set to "no_image" and the camera looks 
at the inside of a 100% reflective cylinder, thus the rays get reflected 
back onto the outside surface (and with "no_image", objects show up in 
reflections) and I get the view I want.
