Ask HN: Hacker side of Insurance Exchanges going live today?

I'd love to hear from anyone that has been involved in the development of these new exchanges. One of those posts on the technology stack or high scalability posts would be great. I've read so much about them and the influx of people their expecting, and I'm tired of the major media spin on their flaws. Would love some first hand material out there, but I haven't seen anything.
