Yeah, happy new year ;)
Not sure if you will even see this, but I wanted to suggest a little experiment you could do with your tech. If you stop and think about it, each cell of the volume is essentially 6 directional lights with equal solid angles. So with that in mind, you could apply a physical microfacet BRDF to each light, then weight and combine their contributions. While that is more expensive, you could apply arbitrary BRDFs with this approach. Care to give that a try? :)
How about now in 2013? Still alive? :-)
Happy new year! ;-)
Yep, still alive, just no time these days. A full time job and a 2+ hour daily commute means far less time for out of hours mad science :(
