If contacts discovery is somehow solved, then I can see potential options of using short range comms (eg bluetooth) for connectivity. Basically all ideas I have are: 1) somewhat central server(s) 2) always on plus constant updates (what briar seems to be doing) 3) every node knows large part of topology (not very scalable) I am wondering if I am missing something in briar’s architecture
