I've created a basic Vassal Module for Descent that would let folks play across the net as long as all players owned the game and expansions being used. http://www.vassalengine.org
You can build the quest map using tiles and stock it with items, obstacles, treasures, monsters, etc using a drag and drop interface.
All of the tokens and pieces are present as are all the player decks with only the names of the cards.
I know this isn't optimal, but I've heard the this is a requirement from FFG for any vassal module for their games to protect their copyrights and IP.
Does anyone know who I need to send it to at FFG to get it blessed off for general release?
