I just released a pile of code called Content Courier. It’s the front-end framework I use to serve up content on this site; a generalized programatic framework for serving up content from multiple databases, using database in the loosest of terms. There’s more information on the site, including a screencast that covers some of the basics.
It’s a bit esoteric in this day and age, I don’t know of many people who haven’t fully embraced a stand-alone CMS/Blog-System to run their site. However, I like the idea that I can switch to another CMS without worrying how to import all my old content.
