OK, this is the old "how do I get more stats than the router provides"

You need something that can measure the traffic that each person is
generating - possibly monitoring the switch ports that they plug into
instead of at the router will do something close to what you want.

And you have a cheap, poorly managed device that you can't run individual
stats for  the end-users using the Cisco CAR trick, nor can you export flow
data using the flowscan application.

I'd say use your pipeline 50 for traction the next time it snows.  Go get a
Cisco 800 series router to replace it and run CAR - see my webpage on CAR at
http://www.geocities.com/djmcdon1 for a complete rundown on how you would go
about that...
