We are using client-side SSL certificates extensively for API as well as browser-based single-sign-on for 20+ employees on a smattering of Mac/Linux/iPhone/Android devices. Definitely some ramp-up and wonkiness, but it's working well.

Also worth noting that infrastructure components like Cassandra [1] and RabbitMQ [2] leverage PKI as well.

Checkout our Jenkins client-side SSL cert auth plugin: https://github.com/pantheon-systems/certificate-authenticati...

bcfg2 works well. It aims toward 100% fully managed servers (i.e. package dependency management, full /etc management) more than Chef/Puppet (but other than DoD/banking, 100% management isn't worth it). Other reasons I prefer Chef are 1) solo mode, 2) more dynamic recipes with ruby 3) more out-of-the-box resources (dirs, files, templates, users, etc)

How about having checkboxes instead of radioboxes for the different providers, and some way to zoom between them. That might get you closer to something like http://www.kosmix.com/topic/fifa_world_cup or http://www.evri.com/sports/soccer . It's a pretty good idea, but hard to compete with companies like kosmix and evri that are crawling and parsing tons of data.
