It's been a bit off my radar, but I recently came across this article about CoderDojo and a Lullabot podcast with some very well respected Drupalers along w/ Coder Dojo folks. Being that our Drupal programs have been dormant for a bit, while the Coder Dojos have really established themselves, I think would be good idea to review and revise our ideas/definitions for our programs to be more in sync with programs. That should also make it easier to re-enter the scene and collaborate/leverage their resources and events.
There definitely are some differences (our programs should not exclude old folks!), but I think the more we don't have to reinvent, the easier it should be to ramp up and sustain with limited resources.
