Hosting modules internally Our company is looking to use Drupal as a platform going forward. We plan on making some modules for in house use only i.e. A module to talk to our holiday system. We wanted to know the best way to host these internally so people can browse the modules. Is it possible to get Drupal to report when a custom module is out of date?
If you want somewhere to host modules you could use distributed version control such as Git or Mercurial to store them in a repository. 

You can then use drush make to build the site with modules hosted on drupal.org and from your repository.
