Has anyone started to add support to Emacs so that Google Drive can be
treated as a usable directory?  Using dired on a development instance of
Emacs 24 yields the error message: "Format specifier doesn't match argument
type"

I have to confess that I love the concept of editing some files on my
desktop computer at home, grab my laptop and head to lunch at some local
spot with wifi and continue to work on my documents WITHOUT having to do
anything special, like use Tramp or a source controlled environment or
sshfs, etc.  Of course, one has be aware of privacy settings so that you
either make the documents deliberately public, deliberately private or
something in between.
