Guess I'd have PoF or use ntop's Web GUI to fingerprint hosts. Too bad
the FIOS router doesn't support flows, ntop's flow facility would work
well. Cheops-NG will let you map your network and see what services
are running internally. These are all pretty useful on a larger
internal network.

Dsniff is going to have tools for targeting specific items; e.g.
URLsnarf to list what URLs users are hitting, mailsnarf for SMTP. In
your shoes I would have it in writing from someone at the company that
they understand that you are going to be looking at sensitive traffic
that may be confidential or embarrassing.
