What you seem to be looking for already exists. A traffic anomaly
analyzer that is able to inspect traffic up to Layer 7. Check out a
product called Reconnex. This may do what you are looking for..
You may run in to confidentiality and privacy issues if you start
capturing actual packet payloads. You may want to talk to your legal and
HR departments before doing this.

Subject: Packet Payload
Im posrting this to the pen-test group, rather than firewall or IDS
because it covers many areas.
Id like to see what the pro's think about capturing and storing packet
payloads from firewalls, ids, etc... everything rather than just loggin
the incidents.
Im trying to explain to my management how useful the payloads could be
if we were ever to really need them, say from a forensics point of view.
To give another example, one time I was seeing lots of firewall drops, I
could tell what ports, src and dest. but no packet data. To everyone
involved it looked like a worm trying to spread.
Well in the end it wasnt, infact is was something that was nice to know
about, but it was not hostile traffic. But if I had been able to see the
payloads i could have seen the data request and known from the start
what it was, or was not.
What would be really great, is a whitepaper covering this, or enough
info/facts that I could throw one together.
thanks!
