Odd that myself and some friends were talking about this very thing tonight. Great to see there has been/is some thoughtful discussion about the idea.
Now, believe me, I don't want to hijack a thread... but underlying requirement of a continuous viable economy really does have to be a part of the decision making process for this idea. If the economy isn't designed to remain viable for the long term, an app like this is irrelevant. I've been disappointed that thus far i see no indication of permanent decay in the game. It has long been my belief that no mmo game economy can remain viable for the long term without permanent item decay. It was one of the things SWG did right. I hope as the game develops, we see it here.
I love the idea of BW having an official app... that way I won't have to pester my coder friends to make me one!
