church managent software

I was thinking about using Drupal for a highly customized Personnel database and thought it sounded similar to a Church Management Software in some way. Has anyone explored using Drupal as a Church Management Software? With CCK and Views what it is, the ability to customize has become rather broad and may be able to handle something of this magnitude. I know some use a CCK/Views ability to manage projects elsewhere and I started the personnel database discussion on the Consulting and Business group.
