I'm working on similar, and -also- "desperately looking" on reliable tools catching this kind of statistics

Prospected tools:
    Free:

    NTop (indeed...)
    ipaudit (http://ipaudit.sourceforge.net/ipaudit-web/) Reliable, simple but limited
    NetraMet (http://www2.auckland.ac.nz/net//Accounting/ntm.Release.note.html) Interesting, but ugly

    Not free:

    inmon (http://www.inmon.com)
    Compuware Vantage xxx products (http://www.compuware.com)
    Cisco (TBI)
 
Notes:
  A good analysis (but outdated) at http://www.caida.org/tools/taxonomy/
  Few solutions can manage RTT, even less can manage jitter, latency, QoS
