aegir

Dave Hall will discuss what aegir is, why you should use it and how he uses it. Aegir allow system administrators (and developers) to quickly and easily manage the deployment and updating of their Drupal sites. If you are running more than 10 or so drupal sites, you probably should be running them in a multi site instance with aegir, if you don't believe me, you should be convinced by the end of this session.

Dave has been using aegir since the 0.2 alphas to deploy and manage the largest know production multisite instance of Drupal with almost 2100 sites running off one code base.
