Thanks Jasdeep. I like the way you call out "sweet spots for adoption". As you have recognized, and thanks for this, I am trying to balance the SDN debate. It's too much like rose-tinted spectacles for me at times. Consequently, I'm trying to ensure that you know about some of the adoption challenges, so that you have time to work out ways around them (and I hope you consider Cisco Services to help you navigate the challenges).
