modpack permission - can I distribute modified config files?

Can I distribute CCraft in the modpack for my private whitelist server with modified config files? This might mean changing things like rednet range, not just block IDs. I thought I saw somewhere that I couldn't do this, that nothing, including config files, could be modified, but that doesn't seem to make sense and so I wanted to make sure. Also, I can include custom stuff in .minecraft/mods/computercraft/lua/rom/, right?

Oh, heck….
The config files are fine to change. That's why they are there, so you can make changes on the end-user side of things. It is just said that you are not allowed to modify or distribute the classes or code in any way.
