Just downloaded Knoppix-NSM, a bootable Debian .iso for network security monitoring. I saw an article about it in the October issue of Information Security Magazine. Includes stuff like Snort, Sguil, BASE, etc. Very clean and trimmed down from what I've seen so far. I'm going through the HDD install right now, and will soon throw it on my home network.
I'll update the masses.
I know you're out there.
