What about using "netstat" to see an accounting of the incoming and
outgoing bytes. For example, "netstat -nvbI ne0":

Name  Mtu   Network       Address               Ibytes     Obytes
ne0   1500  <Link>        00:40:05:4b:34:2c  157954483   40302030

(This reminds me; I wrote a script that recorded this accounting info
several months ago; now to write another script to graph all the info
that continues to be recorded :)
