[K12OSN] how to determine bandwidth usage?

[Huck]

Not one to normally answer one's own questions...

ntop at http://www.ntop.org/  is a juicy little app with a web interface
that does nifty stuff to report your network traffic and the like!!!

Just got it installed and running in 10 minutes after returning from 
lunch! *Yay* I wish all apps were this easy to install!
