I have started a soft launch of Web Project Mechanics (WPM) on Codeplex.  I am taking the web content management system that I have used for many clients and turning it into a project, then I will evolve it into a product.  Right now, the source is a collection of requirments from many clients and projects.  I have been able to unify most of my clients onto the current version of the tool.  At this time there are over 100 sites runing WPM.  While not a fully-fleged product, the code base is over 4 years old and has been reworked numerous times.  The big challange now is to create a product from many successful projects.
