I personally would like to see some love for 3delight/renderman compliant renderers as well...
Well last time I've tried, before year or so, still it was a practically impossible to match Mental Ray, using 3delight's volumes. Wasn't even close, when it comes to speed, quality, memory consumption... Don't believe anything changed to this day. Rendering of millions of points instead of voxels, that might work, but that's probably sufficient for light smokes, nothing else.
As an rule of thumb, Renderman + easy an fast volume rendering = kind of oxymoron. Or, looking from flip side - volumes are only aspect of MR, which, very personally, I'm still keeping in good memory.
