Btw: Funny how the discussion rolls on, while the guy who opened this thread seems to have disappeared....
He vanished right around the time everyone realized that not only were we owed the 200+ BTC that were held back, but also the 400+ BTC or more that he was paid for mining when he was not contributing.
He probably disappeared because he realized he ain't getting nothing.
He vanished because he wouldn't or couldn't prove he owned either address so there was nothing more to discuss. The consequences of having signed either address would be an admission of fraud on his part, which is a crime by every nation's government on this planet, Bitcoin-related or not.
