Virtual machine image might be the best you can get AFAIK. It's also 
very possible that binaries take much less space than sources (which 
have other advantages, OTOH).

I still don't understand why nix, nixos, nixpkgs (and perhaps others) 
aren't within one repository. It was so in svn and the interdependence 
not expressed in the VCS can IMO cause problems (although one can 
synchronize by time of patch creation).
