Any reviews of Practical Intrusion Analysis by Ryan Trost?  I was wondering how people thought it compared to previous IDS/IPS books (notice I said "IDS" and NOT "SNORT")?

Flipping through it at Borders, I do like the amount of ground covered!

Anybody use geospatial intrusion detection (the usage of geographical endpoints for a measure of IDS/IPS analysis)?  I skimmed the chapter and might simply buy it for that one chapter.
