Thanks for your question @paulkaefer. Sharing in SAS Drive isn't really sharing links to other artefacts in SAS, as URLs. It is a means of making objects visible, and accessible to other users inside the SAS Drive visual interface. Take a look at the part 2 post, and I think you'll see how it looks, and that should answer your question.
You mention the organization's network policies in your question; sharing doesn't change anything about the networking set up, but perhaps you mean the organization's authorization (or security) model. As discussed at some length in part 2, sharing DOES alter the organization's security model, and it I think it will be popular in organizations which have relatively open, less formal security model designs. Very formal organizations will want to know about Sharing, and may wish to consider disabling it, to prevent users from sharing their own content with each other, or 'publicly' with anyone who is an authenticated user and is in an existing group, ad-hoc. I explain how to do that in part 2. Users cannot share content with 'everyone', or 'guest', or 'authenticated users' in SAS Drive - I tried that as one of my experiments, described in part 2 - those constructs are not in the list of individual users or groups with whom you can share an object.
