It's a little quiet on the list today. May be everyone's taking an 
extended "Community Day" or something. Anyway, I'm looking at generating 
some network usage statistics on an open network with a large number of 
users. The data I'm looking to collect is

  Source IP
  Source Port
  Destination IP
  Destination Port
  Application Protocol

of each session or flow on a 15 minute basis. NetFlow is close to giving 
me with this, but lacks the application level protocol information that 
I'm after. Any thought, or suggestions on how to collect this data?
