I have looked into this too but not very hard. Just enough to hit some dead ends. So if you find something please let me know. A suggestion to look at is StarWars Episode 1 CD. I think they did something like that where they put some sort of cert on a CD and used that to authenticate you to let you into the website to see Episode II previews. This might be a start.
