A simpler solution is to use disk imaging. If you are truly making all the
boxes with the same technology then a disk image of the current best-of will
due the trick. Then you can send around a new CD every week with the new
image. Just use a boot disk and then DD the new image on to the drive.
On a different track you could place the image somewhere on the net and let
each site download it. They should be able to get at least 56k access to
the net very cheaply. An overnight download would do it for you.
