Under synaptic (for debian-based systems) you can see the three
separate cross-platform sections.
There are similar tools for Fedora-based systems and RHEL-based (Red
Hat Enterprise Linux) systems.

apt-offline is an Offline APT Package Manager
apt-offline can fully update and upgrade an APT based distribution without
connecting to the network, all of it transparent to apt
apt-offline can be used to generate a signature on a machine (with no network).
This signature contains all download information required for the apt database
system. This signature file can be used on another machine connected to the
internet (which need not be a Debian box and can even be running windows) to
download the updates...
Also see apt-zip...
Update a non-networked computer using apt and removable media
These scripts simplify the process of using dselect and apt on a
non-networked Debian box, using removable media like ZIP floppies and
Also see aptoncd...
Installation disc creator for packages downloaded via APT
APT removable repository creator and package backup tool for Debian based
This tool will allow you to create a media (CD or DVD) to use to install
software via APT in a non-connected machine, as well upgrade and install
the same set of softwares in several machines with no need to re-download
the packages again.
There are lots of tools to help you build .deb install files, a.k.a.
are tools for developers to simplify the process and even ascertain
dependencies (search for "ceve").
See customdeb, debtree, packagesearch, and paco, while you're at it. I
highly suggest running synaptic if possible and look up search terms,
"debian," "package," etc.

On one hand, it would be very convenient to have a CD-ROM or DVD-ROM
of software to install. On the other hand, that collection will
quickly become outdated. Look at how fast Mozilla/Firefox software is
updated. For GNU/Linux platform, as long as the updates are pushed out
to the respective repositories for the disribution in question,
updating is trivial. Sometimes it's necessary to update software as
quickly as possible for security reasons. Maybe a CD-ROM or DVD-ROM of
software to install with links to the respective software website and
instructions to check for updates would be in order?
For educators who are comfortable assisting with the administration of
computers, and If there's little to no internet connectivity, you
might ship them a set of software on removable media and give them
instructions for installing and/or updating software.
For educators who don't want to assist with computer administration or
who won't have administration rights, but do have an internet
connection, even if slow, have them put the removable media into the
computer and have someone remotely do installing and/or updating
I've not really addressed Microsoft products. I don't mind doing so,
but I'm more focused on GNU/Linux and other open-source operating
systems. Don't forget, Microsoft Windows XP end-of-life for support is
scheduled for April 2014
P.S. I've yet to publish my forthcoming review on Skolelinux.
