For your first question, I don’t know. Probably not anytime soon.
For the second, the answer is sort of. The plugin supports full access to the Leap Motion API in C++, including getting images. However, there is nothing in the plugin yet which makes these images easy to use in a scene. You would have to decode the images, and display them in the scene, probably on a textured quad, and make your own shaders to integrate them properly into a VR or AR environment.
