Hi Jo, yes we will be releasing Drupal modules soon. The session we had on DrupalJam IV in Enschede was more conceptual and had us focussing on commercial possibilites and added business value. Our next step will be working out a plan on how we want to release what we have, so everyone can look into it, or hopefully improve it. You will be hearing more about it soon (we have a coffee appointment at Krimson's in april ;-). Meanwhile, we will be adding stuff at www.opendover.nl in the weeks to come.
