Snort already does this, and we have proven people aren't really interested
in this.  This is why I am recoding a threshold into SPP and its reporting
of "TCP Stealth" (aka TCP anomalous packet) detection.

Uh...  You didn't just use that phrase.  I *know* you didn't just use
*that* phrase...  ;)

Link?  Sorry, I missed it.

I have an idea on short-longish term packet storage.  Of course this is
in the context of port scan detection and reporting.  Does 1.7 or beyond
have any facility for referring back to a previous packet?

Also, I figured out why I was getting double alerts before.  The TCPDUMP
log facility was sending a "LOG:" message to syslog because I don't send
a packet pointer with the alert.  REALLY annoying when you are already
logging to syslog, and I'm not sure of the benefit regardless.

How can I get snort to log EVERY packet it sees?  Also, how can I get it
to log packets in separate files like in the old days, based on host?
Currently, I seem to be getting a lot of "Destination Host Unreachable"
messages, and I'm trying to figure out why.  I have the tcpdump log
set up, but it doesn't seem to consistently log even packets that generated
an alert.
