Nope, can't say that I can. Never had a need to use any. Whenever someone is using too much bandwidth in my network, I just log into the core router and disable them from being able to be on the network until they come to me and tell me why they were making my internet connection slow.
I don't mind other household members using the connection I pay for, they just can't be slowing down the network with their bittorents and whatever when I want to use it, when they aren't footing some of the monthly bill.
