A new feature has been added that allows admins to create space combat zones. This follows the same rules as bandit combat, except you cannot board disabled player ships. Rules can be found here. Note that it includes a stipulation about not arresting or attempting to kill/capture people while using this area.
This is the first area for space combat. It is a 5x5 zone (25 systems) that allows space combat per the rules I linked above. There are also hyperlanes between Derra, Petabys, and Serroco now. Good luck!
