I use global ambient for architectural exterior fly-arounds and it's plenty good for our clients.  the wind looks great.  I do use antialias on the objects, but not the texture.  Basically I import the broadcast settings into the 'user settings' then I turn off motion blur, and texture antialias, blurred reflections, maybe drop the number of glass refractions down to 5... but then I am rendering as 720x540 pixels and of course HDRI or Radiosity or even GI would look even better, but what I produce already makes my boss and clients and co-workers quite impressed.

Belino's work is far beyond what I need as an architect... but they are incredible clips and very very very well done.  My bosses don't want the fancy camera jiggles and spins, but then, I'm focusing on architecture, not on 'looky what I can do w/ this camera'.  My hat's off to Belino.. .and I look forward to what he will produce in the future.  his 'tests' show me that theoretically one could produce an impressive animated movie on one's home computer using only the tools he does.
