Are either Jorb or loftar familiar with forum gold and how it functions on d2jsp.org?
I made a post on the apples to oranges thread asking for some information (viewtopic.php?f=35&t=34650)
it then came to my attention that it's actually not a bad idea and that Jorb/Loftar could make some money on the side, while at the same time helping everyone trade a little easier.
It is a currency system where the entire supply of the currency is introduced via donations to the developers.  It is not pay to win.  Eventually there is a large enough supply of Forum Points that you never have to buy any yourself.  You can sell in game items to others to gain your Forum Points initially.  This is the key.  
This currency can then be used to trade with other players for in game goods, who can then trade that currency with others, etc.
Example.  Player A buys 500 forum points for X price donation.   Player B is selling a pearl.  Player A then pays player B an agreed upon amount of Forum Points(FP) and then player B gives player A the item in game.  The forum points would be tied to your forum account and visible to all users.  
I'd like to mention that the trade system is very much currently worked out to what most people feel is a fair reward for time involved.  There would not be a giant tumultuous transition period where all prices are fluctuating violently.  Only a small change as the system adjusts to the new currency system, that still very much uses the currently adpoted ratios for value.
The name might need to be changed so that it is not immediately equated with the "points" system that is currently alive and kicking.   There would obviously be an initial settling phase where this new currency has a ratio compared to the "points" system until most people are only familiar iwth the forum currency's price system.  The relative prices remain unchanged.  Flotsams are 40% of a pearl in both systems for example.   whether its 20 points vs 50(current system), or 400 FP vs 1000 FP (hypothetical new system).  This ratio of points to FP would entirely be determined by the pricepoint jorb/loftar set for the supply of their currency.   If $5 buys 10 FP, or if it buys 1000 FP will largely influence how much FP someone is willing to sell a pearl for.   I hope this makes sense, if not i'm more than willing to answer questions.
The only problem I foresee is that d2jsp has a small mod staff dedicated to settling scam disputes, where screenshots and proof are required to get the other person's account in trouble.  Forum Trading should be SACRED.   At least if using a currency that involves donations of real money to the developers.  I'd hate to remove the possibility of being oathkilled during a forum trade, but a system like this would need rules to remain effective and fair to all parties involved.  I'm interested to hear what you guys have to say.   
Shit idea?
GGnewbcomeatmebro?
at least in diablo 2, worst case scenario, they scammed your item and or forum gold. (which resulted in their account's currency being locked/banned until the scam repayed, 95% of the time)
In haven and hearth, you could get scammed your forum points, get murdered, your village raided, and congress informed of how madbad you are.
