For simplicity and the fact that some older machines that can run Mint 10+ don't have DVD drives, is it possible to create an install CD that installs the OS basics, then (via scripts?) loads up the rest via apt-get or synaptic after the user chooses what they want from the LM DVD package-set? (i.e.: The installer would allow the user to select MATE, Cinnamon, Gnome3, Unity, Fluxbox, LXDE, etc.) Whilst MATE seems to be getting better and better (my issue with MATE going 50% gray between login and wallpaper load has vanished; perhaps the latest version has stomped that pest?) others might need something lightweight or Mint would not work well.
With broadband so common nowadays, this seems to be a valid question to raise, even if doing such an install would take a fair amount of time and potentially be quite interesting... in the Chinese sense.
