I attended QCon New York in June this year and spoke about loosely-coupled Identity Management. I was also interviewed after my talk by Eric Newcomer, and the video of this interview has now been put up by InfoQ (the organisers of the conference).
The video is here. The transcript of the entire conversation is right below the video, so click on the "plus" sign to the right of each question to see the full text of the question and my answer.
I'm glad I got the opportunity to rant about SOA and how badly it has been misunderstood and misapplied by the industry.
I also managed to get a couple of sentences in about Identity Management, which I what I went there to speak on :-).
