SDOM has gone public! It's being hosted by the gracious people at Savannah nonGNU. Please go over there and take a look -- it's currently only available through anonymous CVS, but I could really use some feedback, particularly on the aspects of the design that I've documented so far (I'd link directly to the home page / docs, but I'm still waiting, I think, for a Savannah cron job to make it publicly available).
