fluid rendering: handware/software mix

Many Most people who've worked with fluids, have noticed that it looks better in openGL than the render... in some ways. I'm refering to smoke, not more shader based fx like fire. Smoke will have some details that seem to get lost in software render, but software render also has the benefit of smoothness of gradients and propor lighting. Those 2 key aspects keep up software rendering. My friend at work was talking about trying to hardware render his fluids and said it was almost good enough. I played around and came up with this.
hardware render for the added detail and blur/add it into comp over top of the software render. I haven't done this on production level stuff but on my initial tests the results are promising.
Here's one test frame, I'll try to get the render online.
