>Hi, i need a software that say me "you have 90% of broadband, 15% uses MSN, 45% HTTP, 20% skype, etc". Thanks
There are several programs which Google will find for you. Search on bandwidth monitoring software and similar terms. I have used and quite like NetLimiter which includes the ability to limit bandwidth usage on a per program basis.
