Hell of an idea. You get filing sharing through an RSS feed. Add files to the folder, links show up in the feed, an aggregator/reader d/l’s the files. Neat, clean, fast. Of course Box.net costs money and is likely to go the way of other online storage schemes. But the idea is sound. It could use more security and encryption too.

MAKE: Blog: RSS feeds to online storage…
Box.net’s filefeed lets people easily subscribe to your shared files through any web or software-based RSS reader (including firefox, my.yahoo, newsgater, feedster, and more). Distributing files through filefeed is easy: just add a file to one of your Box.net shared folders and all of the subscribers will instantly receive a link to that new file. Imagine the possibilities… share documents with your blog’s readers, send brochures to clients, syndicate recent photos automatically to friends and family, or simply use RSS to sync up your web folder with another location.
