I resigned as Chief Scientist of Solera Networks May 8 this year --
mostly because I was not allowed to have any freedom, including working on
free Linux projects. 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.
Jeff
