As I just reported over at The Aquarium , Eve and Marina recently published Federated Identity Through the Eyes of the Deployer - what it is, why you might want it and what questions to ask as you architect a federated identity system.

What you might not know is that Eve is also a talented musician, shining even when accompanied by those less gifted in the art , such as here, at IIW2006b : Here be the lyrics .
