Reminds me of the packet networks that we hams used to build back in the BBS days. Most of the stations went off air with wide spread commercial internet service and operator turn over, but there's a renewed interest with newer, cheaper, radio gear come out.
Also there's many cities with a first responders mesh network.
I'm a little disappointed, though, that at least local to me most of the interest centers around hacking the old WRT-54G rather than more modern and powerful gear.
