Thank you everyone who contributed to giving us a heads up on this story. The development and distribution of Y'z Dock has been cancelled.
It seems that a Japanese law firm has emailed a Word document to M. Yamaguchi to stop development and distribution of Y'z Dock. The header information in the email appears to be legitimate. If it were not in Japanese (all blocks on my system) I would have posted the email. I'm sure you will understand that in order to protect his family and interests, M. Yamaguchi has officially stopped development on Y'z Dock as well as distribution. --KaosAD
