I get that, but I'm talking about: if I built a server app (or had a Nostr relay running) on one machine, and had a remote client machine that wanted to talk to it over HTTP (or send notes to the relay), that client can't just join the mesh and talk to the server over normal HTTP. I would have to push everything through the Meshtastic message protocol.
Common mesh networking soltions turn your router into a mesh node such that your entire LAN is on the mesh and machines just speak normal HTTP to each other (they just happen to route packets over the mesh "LAN" rather than through your ISP).
I mistakenly thought Meshtastic was a simple way to get that situation without fucking with routers. I seem to have been incorrect, unfortunately
