Flow analysis tools

[Daniel O'Connor]

Can anyone recommend some flow analysis tools?
I am mostly interested in who (from inside my network) is downloading 
how much (ie who is costing us money :)

I have enabled netflow in mpd and I can capture it but I haven't really 
found a suitable analysis tool yet.

I tried nfsen and stager but I couldn't get them to break down based on 
IP, just AS - not nearly fine grained enough for my needs.
