This is why I'm intrigued by OpenVDB
OpenVDB
It's open source, being folded into Blender, and you might say it holds a fractal array of voxels (technically a fast shallow and sparsely populated binary tree). It's currently used by, e.g., Dreamworks SKG to make fire, smoke and water in Hollywood movies.
The neat thing is each voxel can have have non-spatial attributes like color, opacity,
velocity or pressure. I'm sure what we want could be built on Blenders animation engine.

Highlights of this release include
tool to produce and store a sequences of progressively lower resolution grids (mipmaps)
an acceleration structure for fast range and nearest-neighbor searches on particles
arbitrary volume and level set specific segmentation tools
a new binary mask grid type and an efficient point to level set conversion scheme
faster volume to mesh conversion and threaded grid destruction
faster morphological dilation, csg operations and fracture tool
New Houdini nodes: Segment, LOD and Topology To Level Set.
See the release notes for more information.
