Have you ever considered external renderer support? F. ex. LuxRender (http://www.luxrender.net/). It could be very useful, external renderer could provide better quality of resulting images and also possibly lower rendering times. Also with LuxRender you'd have GPU rendering ( #289 ) out of the box. I know that this is a big issue but I think it is worth to consider.
