An interesting new service that seeks to maintain permissions and controls on files once they have been shared. It’s not perfect, but I can see it being very handy in corporate settings that deal with sensitive files — or just files they don’t want the public to see.
One use case that I think is really interesting, as reported by Matthew Braga:
Or, if your boss has a new version of the document to distribute, access to the old file can be revoked.
That feature alone could make a great tool for teams that are collaborating.
