Neil McAllister's column at InfoWorld on RedHat's challenge to Novell with its open source directory product reminded me that I've been meaning to mention Geoffrey Moore's talk at the OSBC called Open Source has Crossed the Chasm...Now What? Neil talks about how companies are replacing non-differentiating pieces of their product offerings with open source. This is just what Moore was talking about, although he takes it a step further and discusses why it's a good thing.
