Unclear on the limitations of Filo

[scarlet]

So in the docs it says that Filo cannot be used for free cable simulation. And then I've seen you post that the requirement is that you have to have objects connected to both ends of the rope. It seems to me then that you could have just two free (dynamic) rigid bodies with a cable linking them, is that possible? It seems like maybe not because in all of your examples, there's at least one static object. Is this a requirement or was that just happen stance? 

You also linked a paper in one of these threads that demonstrated a bow made from cables where it appeared as though the bow was a dynamic object. Would it be possible to make something like this possible with Filo? 

Thanks so much for any illumination!
