Another good example of Anamoly Detection are honeypots.
These are systems that have no authorized activity. Any
connection to (or from) the honeypot is by definition an
anamoly (making them very powerful detection solutions).
In fact, Christian Kreibich has developed Honeycomb, a
plugin for the honeypot Honeyd that not only detect and logs
anamolous activity, but in real time generates IDS
rules based on the activity (specifically Snort).
