Has anyone used Taun wood for flooring?

We are looking for dark flooring and we really liked "Taun Sambuca" but have never heard of the wood. I know it is an exotic wood from Asia and is harder than Oak or Maple with Janaka rating of 1900.

But how is the wood on long run with low-mid rough usage?
How does it react to water?
How does it react to continuous sunlight?
How does it takes the scratches, any polishes that can be used to buff up the scratches?

My builder is little worried about the wood as he has never used this product.
