A new idea has spawned.  While Joomla is great, it lacks some of the features (and has some incompatabilities with) needed to become a truely 'Enterprise' platform.  That's why we've started the project "Enterprise Joomla" or j_enterprise on joomlacode.com.  We are looking for developers to join us in creating a truely scalable and stable version of Joomla!  Any developers looking for more information, you can check out joomlacode.com, e-mail me, use my forums (for now... hint hint), or check out the topic in the Joomla forums.  Keep an eye out for this project, it'll be something worth while...
