So far we have only seen the world of OT lit by the sun. I have seen those beautiful sunsets and the stars sparkle across the sky but not one headlight, streetlight or candle. I presume the handling of dynamic lighting is going to be the job of the engine. What can we expect?

There's no support for lights other than sun and sky yet. We did some preliminary performance-related tests and it seems that we'll have to go for a bit more complicated solution than the one we had originally planned.

Dynamic lighting please.  :D
It makes ANYTHING (No joke) look good.

The question is not if "dynamic or not", but "How?". In such a huge environment, with real time atmospheric computations. Trivial implementation would give a poor performance here.

Assign a luminance to the individual texture pixels based on distance from the light source.

I have no idea if that would work as I don't code. But it sounds awesome.

Thats wrong. You didnt read camenis post. He wrote that it will be a problem to unify global sunlight with additional lightsources. I guess that you have to use a quad based lightmodel with a kind of deffered shading.
So you will paint shadows and specularity later after compositing the whole scene. But thats not easy because of the render architecture.
