Are you backing down from the challenge? :)

I find myself using loops for patterns all the time, as it's one of the 
ways to add a great deal of complexity to them.

You and Jerome are absolutely right; I forgot all about Blender's 
ability to bake radiosity into objects. I don't ever use this feature, 
as it difficult to use and not very dynamic. You have to re-bake all the 
objects if you want to change something. It's a nice feature to have 
though, since you can precompute the radiosity for games and animations.

I agree with you on all points. Blender is coming along quite nicely, to 
be sure. It looks like a kind of media will be available soon (it 
already is for certain test builds), and radiosity will also be 
available in the form of "light cuts," a technique which tends to look 
rather nice and is almost indistinguishable from true radiosity.

As it stands now, Blender's ambient occlusion+environment-based lighting 
works very well. If the sky texture has a bright spot for a "light 
source," it will actually cause objects to cast shadows.
