This is horrible news for DAQRI now.

This is the third product I see using fees against unsolicited mails: an interesting approach indeed. How is this different from previous attempts, 21.co, or even veropost.com which has been on and field-tested for months (without even needing an ICO)?

Very nice indeed. This is the second such product I see after Malloy Hoverbike (http://www.hover-bike.com) and it seems at a more advanced stage. Kudos!
