I have added the Drupal module project to this website. This should make it easy to host your own software on Drupal. The Drupal site itself is using it, or at least it claims so. Regrettably, there is only an unstable release, and that is now more than a year old. I got it kind of working with the latest git version - but there is no CVS integration, the attached view that should list available releases does not seem to work and it regularly gives errors. I am not sure whether it will prove stable enough to keep using - perhaps I should downgrade to that unstable version instead?
