You could try a program called APTonCD. http://aptoncd.sourceforge.net/ "APTonCD is a tool with a graphical interface which allows you to create one or more CDs or DVDs (you choose the type of media) with all of the packages you've downloaded via APT-GET or APTITUDE, creating a removable repository that you can use on other computers. APTonCD will also allow you to automatically create media with all of your .deb packages located in one especific repository, so that you can install them into your computers without the need for an internet conection." - Kale
