Reticulum seems like a promising protocol but I doubt it can be used practically as a mesh over packet radio at low baud rates given its asymmetric encryption suite.

Constant key exchanges, message acknowledgements, and large payloads over standards like AX.25 or FT8 would quickly congest a given frequency using off-the-shelf analog equipment that requires audio mod/demod. But it would probably work fine for more traditional, client-server traffic or simplex traffic.

It seems much better suited to digital traffic in the 900mhz+ range a-la Meshtastic or Arednmesh.
