I can find a group of experienced developers to get us a proposal on the same exact authenticator functionality/app if not more. I don't have much time to do that nowadays but would do it if enough Nemers support the idea of having competitor proposals.
I think some of you missed, that this project is not about authenticator, that's an easy part and if you have ready deployment could be done quite quickly.
As far as I understand this project is about building a framework that will simplify development of other applications on top of nem.
I encourage on reading and commenting in the thread
https://forum.nem.io/t/nem-framework-community-proposal/5174,
they've also uploaded a plan
