Hmm some times custom hardware is needed for switching just of the top of my head you not going to impliment CAM on a bog standard hardware are you.

I could imagine some custom FPGA based modules that you could reprogram on the fly when you needed to regonfigure your networking hardware I am not sure what that buys you networking quipment doesnt have the scale that say a standard pc does apart from maybe acess level switches.

At this moment this seems to be more of a point and drool interface for those that cant hack IOS or pass the CCIE exam.
