Ask HN: How to use EC2 images as a marketing tool?

OffScale is developing a new breed of database management and automation tools. We're looking into ways to make the trial experience as easy as possible. We have just released a precofigured EC2 image available as a way for users to try our product.

We'd love to get some feedback on this approach: 1. How can we make the experience even better? 2. If you have experience regarding EC2 as a marketing tool, did it work for you? What have you learned from that experience?
