I feel that the video is way too long for a "quick tour". After watching bullet points slowly load for the first 30 seconds, I turned it off.
While inquiring HN minds may watch all 4 min, I doubt most users will. I recommend a 30 second teaser which gets the message across, and turn the rest into a how-to video which users can watch if they need help. The UI/UX of the site seems pretty simple, so I don't think people will need a walk through unless they're really dense.
Also the layout on http://www.cloudfireit.com/what_is_cloudfire.html is pretty off balance. Hurts my eyes!
That being said, I like the idea and I'll be signing up for the free trial :)
