Here, I have the use case in mind that a wiki page - say, a Wikipedia article - links to a Jupyter notebook that illustrates some aspect of a programming language, algorithm, dataset or similar.
In such a scenario, having those links point to public PAWS notebooks (which are static) would be useful, but would not provide an opportunity for interactive exploration, so I would like to have some kind of "launch in Binder" button for public PAWS notebooks, which would allow users to explore the notebook's functionality by themselves.
