Keynote to the Future Internet Forum in Athens in March 2014. Presents current opportunities and challenges of SDN for (national) research and education network operators. Outlines NREN's peculiar context between academic institutions, researchers, and vendors. Suggests to leverage the hype around SDN for setting up collaborative community fora, and to look for innovation potential at the "fringes" (as opposed to the mainstream) of the SDN wave. Closes by outlining a few issues with testbeds in general.
