Google Doc API Single Login -

here trying do: create application can pull down single predefined google document.

desired approach:

1. create app automatically logs google drive document owners account.
2. once logged in latest version of document downloaded , presented user through app.
3. this approach means app users can access document without google account.

what don't want:

1. i don't want users have login google drive themselves. want people able access document automatically through app.
2. i don't want document public.

the problem have hit:

all login approaches can find within google documentation require user login through google accounts - oauth style example. can't find anyway of hard coding login single account owner application.

other notes creating web app in php.

any or different approach suggestions gratefully received. thanks
