[development] Drupal staging solution

Hi, Managing the whole chain: Dev - Integration - Staging - Production is a major issue for Drupal. It's one of the Drupalcon2007 conclusion. As we discussed during the Building High Traffic and Scalable Businesses with Drupal , it is imperative for us to have migration methods and tools. At France24 we worked during 2 months to find a simple solution to answer this question. We have mounted a complete dev -> integration -> production environment responding to our needs.
