Cool places to try wifi long shots.

I did some longshots back in the early days of wifi.

You'd need to do a bit of work to adjust the timing, I suspect. At 530km the time delay would be around 1.75ms which would be enough to greatly upset WiFi ;-)

You could probably talk between ends using cheap crappy 446MHz 250mW walkie-talkies though.

This data base could be used to optimally place meshtastic nodes.

You could just send raw 802.11 data frames and then receive them with monitor mode on the other end.

		If I had just re-read Neal Stephenson's Cryptonomicon recently, which I have, I'd say that I'd set up a link using WEP-encrypted 802.11b and hammer data across it with odd little bits here and there designed to generate maximum spy interest. But then the actual message would be encoded by very slightly favouring the high or low end of the spread spectrum map as a kind of terribly slow FSK.
