I'm wondering if there is an easy way to monitor the bandwidth usage of each of them individually. Upon googling, I ran into a lot of suggestions like bandwidthd. I gave it a try and it seemed very broken and basically didn't work at all. I'm basically looking for a "vnstat that works per IP instead of per interface" kind of thing. jnettop wasn't what I was looking for. It doesn't have to make pretty graphs(but that's nice too), just human-readable text is fine. Anyone have a recommendation?

IPFW with pipes. No graphs.

man ipfw

TRAFFIC SHAPER CONFIGURATION
      The ipfw pipe, queue and sched commands are used to configure the 
traffic
      shaper and packet scheduler.  See the TRAFFIC SHAPER (DUMMYNET)
      CONFIGURATION Section below for details.

      If the world and the kernel get out of sync the ipfw ABI may 
break, pre-
      venting you from being able to add any rules.  This can adversely 
effect
      the booting process.  You can use ipfw disable firewall to temporarily
      disable the firewall to regain access to the network, allowing you 
to fix
      the problem.
