Jacob , It's great that you're working on this.
But isn't the biggest problem with security/privacy is that people don't care about it and don't use privacy enhancing products?
Because if that's the case, the starting point should be a viable marketing strategy - which will define the product.
Snapchat is is a good example of this. They wrap a viable user need with a privacy preserving idea with great marketing. Have a look at their site.
