MiniLight is a minimal global illumination renderer, written as an exercise in simplicity. Is there a plugin to export Blender scenes to MiniLight? Or is there another plugin that could be modified to do it?
The MiniLight format is pretty simple:
#MiniLight

imagewidth imageheight
viewposition viewdirection viewangle
skyemission groundreflection
