I give up. It looked promising, but when doing the detailed render it seems fluids still collide with none-existing surfaces.
(look above and to the left of the head)
I draw the conclusion that the fluid sim system simply cannot handle complex obstacles, so I think I'll stay away from it until it matures a bit.
For some reason youtube puked on the video too, I don't understand why. I'll see if I can upload it later.
