Because of some weird need for backward compatibility here, the sdcard needs to be dos/vfat formatted so file perms can not be enforced. This makes USB mounting work on all OSes, but this means many apparently need the "can modify sdcard contents" perm, which is global for the entire sdcard. I think this is why apps can not be stored and run from the sdcard currently.

It would be perfectly possible for the OS to lie to processes, somewhat like chroot, and present each an idealized and sandboxed view of the sdcard.
