Hi Panos, all:
I really enjoyed watching this. As a non-technical DC3 member, I liked seeing more of the "community" side of CNs, but also enjoyed seeing what some of the network architecture actually looks like. From a communications and external relations point of view, I think showing what the nodes look like, the people that host them, the villages they help connect, etc. is really powerful (look at how ISOC promoted the Tusheti Project in Georgia, for instance). And what also comes to mind is how it relates to things like funding and grants. Funders absolutely love to see tangible outcomes of what they fund. With regards to this point, the CN community has so much to offer.
As a suggestion for the future for anyone behind a CN, I think interviewing people in a village where nodes exist, asking them about how it's changed their day-to-day life, and really understanding the community behind the CN itself could be a powerful way to promote community networking (assuming this hasn't already been done, of course).
