Richard Crowley, whom you may know as the Flickr guy behind the Flickr Uploader or perhaps from my Avalonstar miniPrix Kart racing video when I was in California last year for Wordcamp, has created a neat Fuse filesystem for Pownce. Essentially what this does is creates a "drive" on your computer that holds each of your friend’s files on Pownce in their own directory. So if you wanted to access an MP3 that I uploaded, you’d just click Pownce://cdevroe/ (or something like that).
This is too cool.
