Thanks a lot for the help, I will dig my heels into this today. And good point with the caching, I would certainly have had trouble with that.
As for the loosing part, my website still runs ]project-open[ and some other sites run .LRN, so I'm not gone, just a more passive follower with the occasional odd need. Though I have to admit, the SAP world is more profitable and the Drupal world provides much easier access to developers.
