Trading like Metin 2

Seen the discussion last night. I heard AH is hard to get implemented. That's right, but there is better solution IMHO.

Let me buy a special trade tab for my chest where I can put and price items. Trade site parses it by using the same APIs that exists today, nothing new required. Buyer copies link, pastes into the chat. If the player AFK or offline, buyer still have the option to visit seller's hideout. By opening the chest there, buyer sees trade tab, could get items form it for the set price. Seller comes back from the map or the toilet, collects currency, everyone happy. This should be a minimal development, and can make $$$ for GGG for their hard work because the requirement to buy trade tabs. I'd buy them definitely.
