The client team was, for a while, working on a subset of that idea, but for the enterprise market. The project went by the wayside. One of Cisco's main problems is that their idea of innovation is to find a company doing something they like, and buy it. That adds another layer of new executives who immediately start empire building. All priorities are shuffled.
There is no point in taking a long view because there will be another power shift in a year and a half to two years. Anything that can not go from scratch to making a LOT of money in that time is not particularly viable.
If some other company already had such a product under development, Cisco would probably be interested in buying it. Then all the execs would piss in the soup to give it the corporate flavor and we'd be back to the original topic.
