Given our partnership with box.com, we love seeing the integration between salesforce and box getting even more tight. Box.net recently released some Apex libraries that can be used to tie salesforce and box data, giving you more flexibility with how the 2 communicate. Some highlights of what the integration does:
Upload and download files from your computer directly into Box
-Share files privately and securely with anyone
-Easily navigate to, rename, delete or move files and/or folders stored in Box
-Invite, or remove collaborators to any file and/or folder within Box.
