Some use cases:

* Ability to manage attachments in Web-based mail clients, both receiving 
  and sending
* Ability to write a Web-based mail client that uses mbox files or the 
  Maildir format locally
* Ability to write a Web-based photo management application that handles 
  the user's photos on the user's computer
* Ability to expose audio files to native media players
* Ability to write a Web-based media player that indexes the user's media

Basically these require:

- A per-origin filesystem (ideally exposed as a directory on the user's 
  actual filesystem)
- The ability to grant read and/or write privileges to a particular 
  directory to an origin
- An API for files that supports reading and writing arbitrary ranges
- An API for directories that supports creating, renaming, moving, and 
  enumerating child directories and files

I'd be happy to volunteer to edit the Directory component of this, working 
in tandem with Arun's draft for file access.
