Sweet! If I were to get one of these, I would use it to set up a new neighborhood discourse instance out of my house. My interest is in being able to help neighbors keep in touch, socialize on and offline, and help one another out on a daily basis, and build resilience so we are prepared in the event of an earthquake or other natural disaster. For bonus points I would like to explore ways to keep the instance operating when there is no internet or mobile service.
The instance would serve about 100 people and be fairly low traffic on a daily basis, like the yahoo group we use now that gets a few emails a week.
I will be happy to share notes on how I set it up for the benefit of others seeking to do something similar.
