The basic premise of the ping-based drive, taking advantage of ephemeral media i.e. transmission time of a packet, was the idea behind clacks (https://github.com/AlexanderParker/clacks). I got excited to see someone else had a similar idea and explored it.

My approach was more as a p2p system of mutual random packet bouncing rather than using ICMP ping.

Edit to add: I simulated a network of peers and rendered some videos of a single message propagating through the network: https://github.com/AlexanderParker/clacks-tests/blob/main/pr...

Recovering your file in this way would take some time... "Eventually" you'll get it back...
