What level of precision / time resolution are you looking for?

I'm pretty sure I've seen tools that count packets on a link (I remember 
hardware devices like that from a long time ago)--if you find something that 
counts packets, you might write some scripts to:

   * timestamp and start counting packets
   * <do whatever you want to test the bandwidth use of>
   * timestamp and stop counting packets

Divide the total packets by the total time and you have an average bandwidth 
over that time interval.

Like I said, it depends on what level of precision / time resolution you need, 
but I would think you could get some reasonable ballpark figures from 
something like this.

Guess I've included some handwaving there, as I don't know the name of any 
programs to count packets.
