I give u an example like LaunchCast from Yahoo or other stations using port 80 as their service port. This is become a serious problem when bandwidth allocated not so wide. The only thing in my mind, try to apply the magic of patch-o-matic STRING. Examine correctly what packets arrived or what kind of streaming packets sent by server. Block using those STRING.
