Could Apple and Microsoft allow the GPLv3 on their locked-down devices?

It seems that both Apple and Microsoft prohibit GPLv3-licensed software in the app stores for their locked-down devices (i.e. iOS, Windows Phone and the Metro part of Windows). I have heard various explanations for this. However: Would they even be able to allow this license in their app stores if they wanted to, or does the GPL’s anti-tivoization clause already prohibit this?

Data structures for storing finger/stylus movements in drawing application?

I have a general question about creating a drawing application, the language could be C++ or ObjectiveC with OpenGL.
I would like to hear what are the best methods and practices for storing strokes data.
Think of the many iPad apps that allow you to draw with your finger (or a stylus) or any other similar function on a desktop app.

Use Android NDK for portability with iOS?

I am currently planning to implement a little painting app using OpenGL ES 1.1. I believe this question applies to any OpenGL ES project. I am starting development on Android and I would like to know if you would recommend writing the drawing logic (using OpenGL) in C++ with the NDK so it will easier to port to iOS, or to use the Java API and being locked on Android.
