In some downtime at work I threw together a rough proof of concept just to see what it invloves in go[1].. It was crazy simple to get running. I hope people start using it in more places.
Mozilla uses django for many of our web apps, and there's a django app that integrates Persona (formerly called BrowserID). Take a look at the repo, and if you have questions, ask in the #webdev IRC channel mentioned in the readme.
I agree - Persona is an awesome project - and I like anything that is going to take the pain of managing passwords away from me.
I am most interested in python / wsgi integration - if any of your collegues are working on this I will be very happy to contribute.
