Prelude-IDS: Another Open Source Alternative

I've kept the link to Prelude-IDS in my bookmarks for several weeks now. Just recently I saw an article at O'Reilly's ONLamp.com discussing it. Prelude looks especially interesting as it is a hybrid IDS, offering both host and network components. There seems to be lots of documentation and Prelude can be found in the FreeBSD ports tree. I'll report back when I try it out. Be warned -- the Prelude Web server seems unusually slow.
