Jeff,
If you decide to try a network installation, I have found that separating the disks in subdirectories will not work. On your server, try a CS2 directory and add each subsequent disc directly on top of the previous one. When separated, CS2 does not want to work (the install only gets so far or does not even begin.)
Once you have Disk1, 2, 3, 4, Documentation 1, 2 copied on top on one another, you should package the whole thing. Should be a reasonable easy way to get around the problem.
