DayZMod modding...

I've been thinking of scripting my own addon version of the DayZMod. I was wondering if you need any "special permissions" from rocket(Dean Hall). If you don't understand what I mean an example of a addon version of DayZMod would be 'DayZEpoch' or 'DayZOverwatch'.

I've been searching around but couldn't find anything about needing "special permissions". So I thought I'd ask here. Thanks for any advice/ help.
