Force play flash video from start to finish

hi everyone!

We have this wicked project requirement to force play a flash video from start to finish upon user login. One possible solution is to autoplay the video and disable the mouse and keyboard while the video is playing. Is there a way to disable the mouse and keyboard in flash? This means you cannot click anything and type anything until the video finishes. Ofcourse turning-off the computer is out of question. Any suggestion is welcome.
