Sorry, Cities do not scale well for big companies and growth companies.
Cisco needs I think 20 big buildings in San Jose.
There was a large medical testing Lab (forget the name at the moment) that moved out of Santa Monica to Valencia just because of that reason, they needed to scale.
There was a reason most these companies move to the burbs in the first place you know.
Maybe a show case satellite office, but not the 20 to 50 thousand engineers someone like cisco needs.
