OpenCV extension

I am an App Inventor enthusiast, and would like to developp application using OpenCV library. So I am wondering if someone is working on such an extension (not found available one).
If not, would some one be interested to develop it? I never develop an extension, so I have no idea of the complexity, and I am also wondering if there is any license issue to use OpenCV library in an extension.

Maybe OpenCV using WebView?
