darkstat (apt-get install darkstat on Debian)

Of course switching them to Linux or even Apple would help, but then I wouldn't have that guy as a friend anymore.

Sonicwall has an integrated bandwidth monitor that shows how much traffic comes out/goes into each IP address, and I am looking for something similar. My friend's network is a switched network (unmanaged, so no web interface there), and both router and firewall are the cheap kind with no bandwidth monitoring features.
