Following my recent success to compile the latest LyX with QT5.2.1, I am wondering how impractical it would be to port LyX to iOS using QT's built-in support: http://qt-project.org/doc/qt-5/ios-support.html
In particular, is this support only for new applications, or can you take a pre- existing source (such as LyX) and use the framework as is? How about Android?
