You know "some people" just buy Home World transfers right? Pay 14 eur/18 usd to travel to a JP data center and buyout the mb since prices there are half what they are on EU/US. Then transfer back after 3 days. That's a possible 1bil gil for 14 eur/28 usd. RMT circles are doing this as well while no one seems to notice/care.

IMO SE should just somehow prevent this from happening. If item x comes from server y, it should only be possible to sell that item on server y. Crap like this totally screws up the server economy. Now imagine if SE made cross region data center travel available for free. The JP data centers will be picked clean by EU/US players and totally crash their markets (increasing prices). I understand why the JP community doesn't want this and thus SE limiting data center travel to local regions.
