top: direct lighting
bottom: secondary non shadow light placed to illuminate previous shadows

ahm, at the moment i was just testing the possibility so all i did was the other light at the same position as the first, this ofcourse means that this light would shine through walls but i think it showed me that correct placement could achieve something good

also i think boh_havoc has GI planned, its already in but commented out, havent heard from him but it sounds good
