You know what Tux, you got me convinced that you are qualified to litigate this issue in France.  It would have been easy to ignore my concerns, especially when I came on strong and direct like I did.  But now that you have explained the situation a little more clearly it seems like you have it well in hand.

I would also recommend you get some research done for you about any French banks (preferably yours) holding accounts for businesses transacting in virtual goods like WoW Gold, Second Life stuff, Time codes for MMORPG games, micro transactions. 

Vivendi Universal is french, they own blizzard, blizzard runs WoW, that's billions of dollars in virtual goods.  One of which is a virtual currency.  Dofus comes to mind as well, that is distinctly french.  Anyway, if the bank holds accounts for these people, they should have to hold accounts for you as well, non?
