Tomato has built in logging and charting of aggregate bandwidth: http://en.wikipedia.org/wiki/File:Tomato_Firmware_-_Bandwidth_Real_Time.PNG that is probably comparable to what you get from mrtg, and if you are using QoS, it provides some handy pie charts to show what chunk of your bandwidth is being used up by each classification: http://www.polarcloud.com/img/ssqosg108.png (What protocols are included in each classifications depends on the QoS rules you have created.) Some of the less official Tomato builds also support per-machine bandwidth monitoring. On one of my routers that runs one of these builds, I noticed an "enable bandwidth monitoring" checkbox on the form where you create a static DHCP mapping for a machine. I haven't yet seen how or if you can view that data. And it seems like a significant limitation if the data is only captured for statically mapped hosts (the thread indicates they've remedied this limitation).
