Adding to what others have said, I'll note that the ZIPs are not 
reliably up to date. They are only updated by the JSPs after someone has 
attempted to download an out of date ZIP of the same type (raw presumably).

Furthermore, since all new modules are compressed (excepting GenBooks), 
there is not much savings in download size.
