</div>Ton, if you plan a big re-design of the renderer(s), try to get it(them)<br>
CUDA-ble (or OpenCL) since the beginning as was already mentioned in<br>
this list some month ago.<br>
Maybe you can borrow some Tesla unit from nvidia... :-) And don't forget<br>
there could be already a cool name for the IRC channel:<br>
#blendercuders... :-)<br>
<br>
Bye<br>
