My client wants urls site1.com and site2.com that share the same codebase for everything but the theme. They want different node content on each site.
They also want the ability to login to one location site1/user, and be able to update content from both sites there.
Is this possible with a multi-site install or Aegir?
If there are two different databases, it seems that you could not update content from both sites in one Drupal admin panel.
