Does anyone know if an AddOn like this exists, or is anyone interested in creating it?

Net Worth
Short: A calculation and tracking of the value of your account over time.

Using Master Merchant pricing, calculate the value of contents for all characters on the account. Content includes the following for a total net worth:
- Worn Gear and Equipment
- Known Motifs, Recipes, Furniture Patterns
- Researched items (Nirnhoned only is ok, the others are cheap)
- Items in Bank
- Items in Crafting Bag
- Telvar (general conversion value set by player or based upon value of purchasable items)
- Alliance Points (general conversion value set by player or based upon value of purchasable items)
- Gold

As someone who trades a bit, it would be nice to see how my net-worth adjusts over time. Motif prices drop, item prices fluctuate, etc., so a graph view would be nice to know if my trades are making or breaking the bank.
