Anyway, you are right that your multimedia accessing school users will need some good bandwidth, and if it's any consolation to this discussion, I worked in a school where the language lab had a gigabit connection via fibre to the main PDC in the server room (one building away), and still had some useage problems at times (high yield times such as early morning logons, which we solved by logging the machines on remotely in stages before registration ;-)  
 
Hi Paul,
 
What speeds was your network cards? Did you use dual 10/100, or did you have a gigabit network card?
 
Thanks Gary :)
