Good question profmac, I saw mazacoin in the news and remembered this project, after a bit of digging I believe it is the same project! Payu is quoted in an independent article about maza http://www.independent.co.uk/life-style/gadgets-and-tech/mazacoin-native-american-tribe-adopts-bitcoin-derivative-as-national-currency-9165314.html

There is a chance that they have just used him as an expert to comment on another project but I think it's too similiar, either way they have done a fantastic job media wise and it will be great to follow the story.
