If you wanted to look at usage patterns, then FreeBSD hosting a MRTG data collector would be good. MRTG uses SMNP to query routers about traffic seen and generates graphs based on the collected data. It's pretty neat. We have it running here at the University and the usage patters we see out of the residence halls is, well, revealing. If you want to dig deeper, you'll want to run a proxy server, like squid, fwtk, or socks.
