It took 2h.

About 30m to make an OpenFlow controller PC out of bunch of trash, and boot my controller DVD. "ed" wasn't available on my controlled DVD so I made Andy use nano to configure it. That slowed us down quite a bit.

90m to put OpenFlow firmware on a 3780 switch, including walking up and down the hill to VUW get 1G SFPs. 

So if you have any questions about whether OpenFlow/SDN works/forwards packets in hardware - ask Andy. He knows. And has a live CD controller.
