Maybe it would be better to just burn the legions overdrive, installer program to CDs, and include some custom maps, client scripts, etc, with a readme on how to install it all. I am going to update my old mod, and maybe have a server up in a month or two hopefully. I stopped drinking, and doing drugs, so I will have more time to play and mod this again .
I'm not sure how many people these days have CD/DVD drives in their computers anymore. I haven't had one for about 5 years now. I'm sure many still do, but you're guaranteed they'll at least have a USB port.
