Box.net, the online storage service, has updated their embeddable widget with a new group sharing feature for members with premium and professional accounts. Users can password protect a shared folder, which can then be accessed privately by others with the code. Storage owners can opt-in to allow user uploading, which lets anyone with access add files. The company is gearing it at businesses, whereas its previous widget incarnation was aimed at users with social networking profiles.
For group users to keep track of updates to shared folders, each share gets its own RSS feed. Once subscribed, the name and direct download link will be broadcast to any subscribers. Neat.
Note: I have the anonymous uploading turned off on the widget below. Read previous Box.net widget coverage here.
