Has anyone seen Gliffy yet? Go to gliffy.com and check it out. They currently are selling a plugin to the "confluence" wiki. I think this is a seriously powerful tool that dokuwiki should support. They mention a free open source licence but I'm not exactly sure how that works since they are charging for other licences. I'd like to see this in my instance of dokuwiki for sure either way. Anyway, just thought I'd mention it.
