* a separate scene (a bottle, or something) for examples of caustics use (arealights + photon only spotlights)
* an example of portals use with the kitchen scene. IIRC for portals is better to use a sunsky environment and not a sunlamp?
* a warning on caustic troubles (had in mind this one) and explanation why it's better to use fake glass in archviz
Only the 'indirect lighting only' pass part I'm not sure I understand - do you mean to create a PM clay-render which would be then used for "lightening" the scene in compositing?

if you use a 'only photons' spot lamp in a scene, you basically would get an 'indirect lighting only' result. I have not tested this that much.

it's great to improve caustics or Photon Map where blotches are too evident without changing the main lighting setup
