This was our case. Websense blocked all the streaming protocols and
p2p by default.  It was difficult to isolate our legitimate business
traffic from the streaming content sine it was all port 80/TCP/HTTP.
Throughout the morning I was adding in streaming sites as they came
in.

We fared pretty well considering only one customer complaint and we
were able to maintain 92% utilization or internet bandwidth(one point
of saturation @ 98%).
