It would be great to be able to have the ability to share a file that is backed up. It would allow the user to create a link to the file and have the option to password protect the file for the shared link. A timeframe could also be set for how long the link will be valid.
Realbworld example: Let's say I have a large video clip that is backed up by Webroot and I want my mom to view it. The file would be too large to email, so I could just set up a share option for the file that can be emailed to her. She can click the link to get direct access (download/view only) and watch the clip.
