Sharing requirements with git for transmedia applications

In my previous post about the topic I wrote about the abstract requirements of transmedia applications. When talking about transmedia applications I think of many independent code bases serving the same business values on different platforms. They share the programming language independent features like the branding, and the purpose they intended to deliver. The native iOS and Android Facebook applications unlikely reuse any code from each other, yet most of Facebook's features can be accessed without having to learn a new interface.
