The octree tends to be quite sparse (For Sponza, the occupancy is about 3-4% (and it tends to be groupped) so there tends to be quite a lot of empty nodes even higher in the hierarchy. Although this might not be general rule for any scene. Anyways, time to do some coding. Thanks!

Cone tracing is a way to approximate the result of casting many rays into a scene with a distribution on a lobe. This is done by taking samples along a ray, but as the samples get further from the ray origin the sampled mip map level increases. Each circle is a sample along a ray; the size of the circles corresponds to the mip map sampling level

The cone tracing is performed by taking steps along the cone axis, with a step length corresponding to the cone radius, and accumulating quadrilinearly filtered voxel data. The interpolation requires duplication of data to neighbouring voxels, which result in a memory consumption of nearly 1024 MB for a 5123sparse voxel octree with materials.
