+1 on creating a developer centric intro video. Having tried your product, I know that a video like that would get serious traction on a place like HN.
Jumpstarter is the kind of product that just leaves people in awe. I've shown it both to developer friends and to my girlfriend and the reaction has always been the same: "How can I get an invite?".
It's so nice that you're finally in Beta and that you get to show the world what you've been working on for so long. Congrats guys!
