@lizardsquid I've been looking into related questions in the context of mesh networks with exit nodes that give the mesh access to the rest of the Internet. I don't know anything about legal/telecom conditions in Australia, but the big telecoms in the US don't like that idea, which means looking more carefully at what kind of business arrangements ISPs make with each other. (If all goes well, I'll soon have published some background on that topic in an upcoming article.)
