easier for boss hosters, they can use this duey package delivery to send out split plus we can complete trades with someone on the other side of the world is darn near impossible. however back in gms Duey was abused by hackers, so idk if this is still a good idea(lmao).
I would assume an appropriate fee (there was one attached back then I think too) and a tax on raw mesos if sent (Same as stores/trading- can you send mesos with duey? I don't even remember) would essentially make it like a normal trade. I would also assume it's implementation would come with the appropriate tracking so it wouldn't be appealing to people trying to do something.... not good.
