The way cable works here do not let us do that neither. The way I tried it isn't the same way you used, but this may probably lead to the same point. I tried to sniff someone else's traffic using ARP flooding against the switch and simple ARP spoofing. Unfortunately, our cable modems block those attempts and report them to the administrator. Furthermore, I also tried it the same way you did, and I couldn't see anything.. probably for the same reason.. some kind of switched network. But I'm not a network guru.. so I might be wrong :)
