wow, thanks so much for the file!  that's above and beyond.   and your workflow is pretty much what i was tentatively setting as a goal.  i figure it will be quite some time before i acheive a working understanding of  lights and materials in either blender or indigo, but it seemed like a good plan.   i have a few questions:

do you find it easier or more efficient to supplement your blendigo exported xml files with hand coding?

does blendigo port blender sss to indigo sss, or does the indigo sss need to be hand coded?

can you do anything else while rendering with indigo, or does it take up all processing power and RAM?

have you ever used indigo to render something at 2000px or larger?  if so, how long did it take?   if not, how long on average do your indigo renders take now?
