I doubt most of you even know what the most important unanswered question is. Hint: it isn't even related to NVC.
I know what the most important one for me is where is the listing of the accounts trading in the buy and sell transactions so we can see which accounts trade with each other on every trade. I'm pretty sure that would be very interesting to see and do an analysis on.
Edit: I would add that would be nice to see on all these exchanges that allow you to buy and sell to yourself as btc-e is not the only one, in short it has been there on every one I have every been on and tested to see if it was possible.
