Meshtastic is an encrypted communications platform for the Lora RF protocol
Over the years I've had students doing "people net" style meshing,
BATMAN, opportunistic routing, stuff for warzones or emergency coms
for disaster areas.<p>We learned a great place to test this is <i>festivals</i>.<p>Lots of endpoint mobility. New nodes coming in and out of the
network. Terrible 4/4G cell coverage, so few alternatives.  Dead
batteries. Shadow zones. Fairly chilled out delivery time constraints.
Everything you need to tweak your protocols.<p>I hope someone into playing with this will set up a larger scale
experiment at Glastonbury, Burning Man or another big music festival.
