Luxen found this, somehow, and you can tell it's not all there yet, but my real question is.... Why do you need Nougat for the android version?

danstr, at the bottom of the page is "Guild Software" and it links to another site. that site's news page updates maybe 2-4 times a year. Well, I check on in sometimes, and saw the news post about VendettaMark there. Thats how I found it.
