GPS based briar activation for public meshes
EDIT: I am unsure, if I understood the idea of communication of public mesh. When I am wrong, just close the ticket.
Nico recommended to mention public mesh and security slider to prevent heart attacks.
In an emergency case where the internet is down and the electricity is partly available, it could be of interest to save some power. An idea is to activate briar public mesh based on the GPS position. If I walk down the road and I know that a neighbour has briar public mesh, I could activate briar and briar could ask to activate once, every time or only on successful connection. Even if I pass by slowly with a car later, the connection could work without touching the phone.
Switching off could be based on GPS or time based, e.g. 10 minutes after last data transfer. GPS based switching off doesn't work in a bus. If you enter a bus the start position is often the same, but the GPS position is left quite fast. Another guest in the bus could have briar and one could miss data transfers.
GPS based locations of communication buddies are saved locally. To optimize the networks, it would be nice if a public mesh could publish a bit "this client has a fixed location, please distribute". That position could be shared with Osmand.
If you are running briar public mesh and briar there could be security concerns. If I have contact to another client and have no new messages in a shared briar forum and in the public mesh and I walk down a road and come back and I had a connection with a public mesh with "please distribute GPS" and new public mesh messages and I have new messages in a shared briar forum, it could be, that both, the briar and briar public mesh client, are at the same position.
