I've thought of this exact idea myself, glad to see you've done it , hope it works out for ya!
Couple questions/suggestions:
Have you made the video downloadable? You might want to think about it, so people can pass it around in emails, fwd to friends, etc, instead of just the link.
Also, you might want to put that video in it's own page so google can index it. Check this out
