Cool idea. I will keep an eye on it. But how to you plan to make is user friendly for mainstream users?
When developing the app, we made sure to make it easy and user friendly even for those that do not understand crypto currencies and do not want to get involved with it. If you see our demo video, you will realize that the end user does not have to do anything expect have some WiC in his account and make 2 clicks. The app handles the rest in a safe and encrypted manner without the end user realizing what's going on behind the scenes.
