Getting Started with Service Bus. Part 3: Service Bus Explorer

Today I woke up thinking that talking about Identity and Access Control and how your strategy around that affects you (web-) app's architecture without going too deeply into the security lingo that usually comes with it. Here's the 40 minute result.
I start with HTTP's "native" authentication model RFC 2617 and how that's universally bad, with both Basic and Digest authentication having issues Digest being, ironically worse for the overall security strategy. Then I dive into why models that use tokens (or cookies) are better in terms of security and scalability and explore a range of variations amongst those.
Clemens mentions a Firefox plug-in that helps steal session cookies over wifi, but he could not recall the name. I believe he was thinking of Firesheep: http://codebutler.com/firesheep/
A great primer for those new to ACS and federated security. Thanks for publishing this.

This is really a great introduction into ACS and its feature-set on a conceptual base. What I miss the most, are some samples, or better some video demonstration, about WCF and best practices regarding service throttling on Azure. A video only about WCF being hosted in Worker Roles on Azure using ACS would also be great
Thank you.
