Thank you everyone. I wound up learning a lot about bandwidth monitoring. The ideal situation I would need a switch that supported netflow (cisco) or sflow (hp or other). I have a nice hp switch but it was one version below the sflow supported model.
For a network without sflow or netflow switches then the only real way is to get SNMP data off the switch. For this I wound up using Denika (free) http://www.plixer.com/products/denika.php. This is giving me pretty good in/out put data to the internet. But with SNMP I need a second packet capture device to see who is using the most data when things spike. I tested, Prtg, Ntop, but was not really happy with how well the information was presented. Denika seemed to do the trick, they also have a netflow/sflow monitor called http://www.plixer.com/products/netflow-sflow/scrutinizer-netflow-sflow.php which would allow you better reports of who is using the data.
