Yeah, something like APT, with three important differences;
1. Must be able to upload apps, or media files, or whatever through a review process
2. Must be able to charge for apps (although price may be free of charge)
3. A bunch of metadata standards that says things like, if you download a music album put it in Music under Artist -> Album
If someone would develop that protocol all of a sudden a good chunk of power comes back to us consumers/users. :)
