Almost every online RPG I've seen has had it. I was shocked PSO doesn't. Think about it, maybe accessing it through the chat menu in that menu you get when you press start and being able to choose a player, then open a trade window with them. I'm not exactly sure how you'd be able to drag and drop or anything, but it would be a much more secure way of trading. I was shocked when I saw two people trading by just dropping their items. A cheater with no lag can just scoop 'em up and run. I'd say Sega needs to implement something like this...
