We have multiple users that connect to streaming media sites to listen to music in an office of about 60 people (about a third of users might be streaming). We have a T1, and speed has not been a problem, but we want to prevent any problems that may develop. How much bandwidth per user is taken up by any type of streaming media? Have not had too many dealings with this; is there a way to measure it, or can we assume a certain amount? Thanks in advance
