Box.net, the file-sharing and storage system, has two announcements coming later today. First up is the launching of the second version of its Facebook application, followed by the announcement of its Files application being opened up as a development platform for other Facebook developers.
With version 2 of the Facebook Files application, Box.net will offer new file privacy options, which is incredibly important for Facebook users when taking on these applications (and an important consideration for developers as well). As Facebook newsfeeds and profile settings are social by default, most Facebook applications don't allow much room for self-management tools, like calendars, to-do lists, etc. Box.net's latest version will also work well with Facebook's new email-out option as well.
The furthered step of opening its Files application to the developers community will encourage a new group of file-sharing applications that are designed for Facebook's social space, as the box.net service can be integrated into these other applications. The developer's platform is scheduled to be made available some time next month.
