A few moments ago we got all the right people in a hangout to discuss how to
support SD Card access with apps and we have a preliminary design that addresses
the aforementioned complexities, maintains application isolation and allows apps
to use the SD Card without any additional privileges (ie, won't be blocked for
manual review in the store).

Thomas Voß will now shape this into a proper design spec and present this here
in the coming weeks.
