Great news about duping but I'm sure it will reduce dupes but not so sure it will really stop the dupers unless both the old "hacked/stolen item" and the restored item gets account bound.
It would be too easy to implement, and games like Entropia Universe has it already:
1. After putting items/money, players will click "ready to trade", if one player changes an item the box will be unchecked again for the other player.
2. When both players have clicked ready to trade, open a new dialog displaying what items will be traded where nothing can be changed and both players have to either accept or cancel.

is possibly faster with archon? Dunno but got bored of it a bit back...
1 bar is about 21.7 mil xp I think, and didn't quite get 1 bar, maybe~80% (low density run).
Sorry for lag at start, computer was loading:
