This went on for almost 4 years (since 2003). Now that I am independent again, I can work on stuff like this again. I started a new company with John Noorda (Ray Noorda's oldest son) who runs Canopy now. That's my current status. I am an owner and entrepeneur again. So I have a lot of free time and will from now on.
