If that's the case then it should likely be easier to implement as adding a network protocol with ICG would likely be time-consuming. A separate application will allow faster production and possibly more features. The app could even incorporate a QR scanner for use at Generalbytes ATMs to withdrawal and deposit Incognito coins.
That sounds interesting, I've been looking for an alt-coin with ATM integration. A stronger infrastructure should provide a stronger future in my opinion.
ATM integration is the strongest feature of Incognito coin and it should further be expanded into other ATM providers since the API is easy to port over. I believe that the QR scanner feature is already available in the mobile wallet but it would be nice to have it in another separate application as well.
