[Sugar-devel] DataStore interface for HTML5 Activity

[Daniel Narvaez]

As you point out, the main problem here is the concept of file.

My understanding is that with the new file APIs you are basically
requesting a sandboxed filesystem, then you can write and read there as you
please. Though I don't know how the shell would then have access to that
filesystem, to be able to move the files into the datastore.

Chromium must be doing something similar to allow writing stuff to google
drive using those interfaces, though they implemented their interfaces
directly into Webkit.
