There is one question about the atraura project that has not been asked before but should be asked:
Is any other group willing to make the same software for less?
Sofar nobody did make an alternative offer, most likely because programmers in this niche market are still a very rare species

It would be interesting though if there was some competition.....
(i wish i was a better programmer lol)
You do not have to be a developer. How about reaching out to these guys "krypt.co" and ask them to give us a proposal on NEM integration. They are already in the authenticator business and applying similar functionalities for handling SSH keys privately in mobile apps. I bet you they would do it at a fraction of the requested funds if not for free as it will allow them to expand in the crypto world. Someone has to reach out to krypt.co
