Fascinating discussion and hugely relevant... would like to contribute my 3 cents.. We must not forget that by embracing these new work environment solutions we are mitigating the growth of our physical foot print and clearly our carbon foot print, a win win for the environment that we all care about. An excellent Cisco on Cisco show case and in addition we must not forget the 'human buzz' and wonderful energy that these environments achieve. A place we all thrive as social animals.
