[whatwg] Proposal for local-storage file management

If we added the ability to create File objects, which could then be
stored in localStorage (and WebSQL or whatever will replace it), then
wouldn't we basically have the functionality you seek?

What's the difference between sticking a File in the "foo/bar/bin"
property on the localStorage object, vs. sicking a File object in the
"foo/bar/bin" directory in some FileSystem object?

Note that the latest HTML5 drafts allow for storing File objects in
localStorage.
