Sorry but I've been really busy and I'm gonna be even more :)
So... because of the few time which I've got I'll pulish three works together!
ONE
The first is a simple geometry with a totally reflecting material applyied.
The cubemap
In order to get the final result I've used the same cubemap on sketchfab to texture a big cube in my Blender scene. If you need them, you can find them on Humus for free.
For this purpose I've setted up eight different materials but you could also use the same and play with UV's placement.
Anyway, the cube's material is an emitter (emission=1.0).
The light
Another remarkable details: I had to place a point light in the center of the scene because elsewhere the inner reflection were totally black. Try it on your own.
The UVs
Of course, I've unwrapped one sphere and one cylinder at the early beginning. That's necessary if you want save time after, because if you want to bake textures you NEED to unwrap.
Nie vergisst!
The baking
I've baked textures as usual and created the new material (one for this scene); this is a very simple lambert shader with no specularity and only the baked texture applyied.

The SSAO
Oh my God, what's that!? Yeah, now we can use SSAO (like Ambient Occlusion) without bake it. Nice, but what about the values?
As I've digged quite a lot with those values I wish to publish my personal setup:
TWO
The second one is an old model (do you remember about my Christmas 2011 postcard?) with matte materials, no raytracing; this is meant to play with lights only.
The cubemap
No cubemap here! Only some lights around to fake image's lights.
The light
Not so complicated setup, but... there are no rules for this. You have to follow your own feeling about lights and image. For this scene I've used 7 lights (2 spots, 5 points) but you can do what you want and do it better.
The UVs
Only needed for wood texture. No complicate unwraps.
The baking
No baking... :)

The setup for this scene:
THREE
Oh... something new? Ok, this is the same as the first except for texture's resolution (bigger) and for blurry metal applyed to the external structure.
A technical note: in the third scene I've used two textures 4096x4096 each. So... don't worry about texture's management, because Sketchfab is really powerful.
Ciao!
