So it looks like Moveable Type might end up doing what I want it to do. It’s not my favorite solution, though. I was trying to protest the 3.0 license changes, since it kinda keeps Coolass from being able to upgrade without paying $70 or 100. Blosxom was pretty close to what I wanted, but web-based management out-of-the-box is really nice, and the templating in MT is second-to-none.
Need to get commenting working, need to get a few other things looked at, and I’m going to do some experimenting with MTPhotoGallery.
