Agreed - I like NfSen with NetFlow for this.  I can at least mention it, but did I also mention that I only get 40 minutes?  :-)

Agreed.

Agreed - this is especially relevant with tunnels.  I have to pick what I can do in 40 minutes but the backup slides in the appendix can cover other issues.  There is certainly lots to talk about.
