Hmm well tariffs should be split between the lawful factions that own that space, unless agreed by all factions in that space it should go to a certain faction e.g. the armed forces or police or to an industry faction.
As for the tarif collection ya could charge a set price for carrying a certain cargo type e.g. vips then it doesn't calculate for all the stacked items .
worse gets to worse do it by hand get the human military or police to do the taxing then ya dont have to put a script in if it causes that much hassle and then it would add even more roleplay
Please read my posts for the last few i have stated it wouldnt be a capital system for obvious reasons. it would be a controlled set of jumpgates too. why ya dont have to do the whole shibang why not just the proto type that randomly throws you into a random system one way if that is causing you grief.
Programing - this is a community thing if it were to be an all round accepted idea the people with the skills would contribute if they wished.
Why don't you now have a go at making it better with your ideas and skills how would YOU make this work or feel this could work if you were that way inclined. ideas are made to be built on an arguing back an forth is not productive to making more ideas for discovery an potenentials.
