I attented the Agile 2007 conference.  Their were 4 sessions about Lean:

  1. Introduction to Lean Software Development
  2. Lean and Agile in the Large
  3. The Business Case for Agility - The Lean-Agile Connection
  4. Lean Is More - Using Lean Software Developement to Guide Agile Transitions

At the Agile 2008 conference in Toronto, this number double to 8:

  1. Agile Game Development
  2. Value Stream Mapping - Extending Our View in the Enterprise
  3. Come and Take It!  Lean Pull Applied
  4. GTD + Kanban + Round Robin for Product Owners
  5. Future Directions for Agile
  6. KFC Development - Finger Lickin' Good
  7. Estimating Considered Wasteful : Introducing Micro-Releases
  8. Starting a Kanban System for a Software Engineering with Value Stream Maps and Theory of Constraints

I'm really glad to see more experience reports about Lean, especially the pull system as I think this is just revolutionary.  After presenting Lean to lots of people in my company, the main feeling was that this stuff was pretty neat but nobody knew how to set it up.  Well, people have figured it out and, hopefully, we can learn from their experience.
