I just wrote this python utility for keeping OmniGraffle diagrams and Django models in synch. Anyone else like to keep object model diagrams of their database tables? Or of architecture or dataflow? I'm currently scratching my own itch, but I'm looking for feedback and feature requests to see where this might lead.
