We tried even with the hauler(AAI Programmables vehicles mod) and it doesn't transfer to each other players hauler, only same owner haulers...
Would be nice to have a chest, WITH permission to X and Y players to open/close
or a trading building...like Age of Empires, with a mule remember? haha
tech one: Could be a shop, acting just like a chest,
Tech two: with a mule(not literaly), player one request X iten, player Y send hes 'mule' to player X, players X send something in return for it!
I WOULD LOVE THAT!!!!!!
[EDIT-1] We have found a way, inserters, belt and a chest....
still, i and, i think a whole bucket of people would love something more practical like that! that is, if the game aloud something like that!
