I would argue that CEC will never really work since it wasn't standardized and since every manufacturer seemingly has their own implementation. I won't upgrade my gear simply to get ethernet over hdmi but I do think it is a move in the right direction and a feature that people will apreciate. As with anything, only time will tell if it will really work or if it will fail. At this point, on paper, it looks good to me.
Personally, I'm still looking for a quality home wireless router that has a gigabit backbone. 100mpbs is just too slow to use for transferring large files.
