No...as I said, the voxel version is simply a DF3 file with some 
additional headers identifying it as a DF3 file. It will eventually 
support some kind of compression, but not immediately. The "sparse" 
formats aren't compressed, they just store only the non-0 points. The 
overhead of doing so will make the files bigger if more than a certain 
percentage of the file is non-0 density. And the procedural version 
isn't compressed either, it is analogous to a vector format.
