"Battle in a Box": An Idea Whose Time Has Come?

Go here, to Take the High Ground, and read about this really cool project.

  Essentially, the fellow in charge of that blog is trying to make a complete game that you can carry about in a reasonably small box. His original goal was a cigar box, but that proved a bit too small. Now he is scaling it for one of those plastic art supply boxes.

   I am thinking I might be able to manage something a little larger for 6mm (he is using 2mm scale). The rules are really simple, as well. Which we like.
