That selfish was NOT the the OP. It was for general audiency who prefer all the bandwidth for themselfs. We know how most people behave. They do NOT really care what others are doing. For years, I was proud of my QoS because my entire home could utilize my (not so fast Internet) and I always could do gaming, because everything was QoS correctly. Nothing fancy, just separating TCP vs UDP and futher, doing some tuning between TCP bulk vs interactive traffic. Same went to UDP, some separation for gaming/voip/interactive vs VPN (bulk). HTB is pretty decent for this.
