Andre,
that are the two things I like about ZORBA: You can change the propagation model (but does not change too much) and calculate random incidence (diffuse field, will normally give higher values for absorption).
Thank you for your pm, tried to answer but it was bounced.
Yes, I read most of the documents at the end of Bob Gold's list.
