Hmm. I wrote pocowiki a while back, which has the same sort of purpose (lightweight (Wiki/Every)-like engine), but is implemented very differently -- I use POE::Component::Server::HTTP (so it runs its own micro-HTTP server), and the database is stored in memory, using Data::Denter for (de)serialization to/from disk. I also wrote a little (MUCK-MPI)-like preprocessor for use on my website. Perhaps I should post (it/them) sometime...
Update: Just noticed -- Personal Interlinked Encyclopedia? PIE? :-)
