Dan Esbensen and the folks at TTI have built what I consider to be
a very good intrusion detection system.  It is capable of monitoring and
logging sessions, real-time and delayed playback of sessions, alarms with
various associated actions, etc.  You can filter for specific textual
patterns in a flow or filter based on IP address or TCP port.

They've put the documentation online at 
  http://www.ttinet.com/doc/insa_v15_contents.html

The sell it as a bundled system.  It runs under VMS on an Alpha which they 
size based on the number of concurrent sessions you wish to monitor (I'm
not a fan of VMS, but the system is turn-key so you don't have to mess
with VMS unless you want to mung the log files generated by the system).
