Ok, well that post is a blast from the past! :) I think I have seen this a time or two in the past, thank you for bringing it up!
So I am guessing it is a mesh network then? Like Meshtastic? I have dove into the concept several times and we have a running thread over st the TA about it. The only draw back I can see is range without repeaters. I suppose it would be best for more populated areas where it can be relayed? Butthe Meshtastic is a similar idea I think, butit is designed to use add on radios that appear to give it pretty good range. And they use solar powered relay repeaters to make links at further distances.
Yeah we've had a few convos along this line but I couldn't recall your user name so I searched for freedombox as a keyword.
