Want to Create a Live Cd from Knoppix 4

Hi
We have started a new linux community in our college ,Infact most of us are quite newbies in Linux.We have set a goal to create a Live Cd from Knoppix 4 with all its capabilites and + some educational programs & games , - some existing programs.
We need to change the existing Live Cd wall paper too.
We have got a Knoppix 4 CD.
Will we need a Broad band Net connection to Accomplish this task??
Or can it be done without a net connection ( we dont need to update all the lib files and similar stuffs)??

We have written much on this topic.
