Implement "share via" Button for Pictures as known from native Android, WP and probably IOS Apps

Hey Community,

When developing an App for Android or Windows phone it is fairly easy to integrate a "share via" or "send via" Button for a Picture that lists up all applications installed on the device that can send pictures.
Here are a few Screenshot to show what I mean (WP/Android users might be familiar with it):





Is there any way to integrate that into Unity?
If not, how would you achieve that?

Using interaction between Unity and Android/WP might be a workaround, something like AndroidJavaObject.CallStatic etc., but I would prefer a cleaner solution.

Any thoughts?
