Team Talk for iOS, Is It a Sham?

A month ago, I posted an audioboo in regards to Team Talk for iOS and its development. To this day, none of us in the blind community have heard nothing from the so-called developer who's blind and claims he's working with barewear. Numerous attempts have been made to communicate and all he does is ignore. We're all starting to believe he's full of it, what is your take on this?
