Sounds reallly nice!!

Decentralized is probably the result youre looking for when building mesh networks?

Idk if there is an open source broadband technology, but it is interesting.

I wondered if Bitcoin did need addressing in the first place, because everything is broadcast based. This would make it alot easier to create a decentralized physical network layer for Bitcoin (currently the highest priority I think) as it is only required to send bits of data instead of needing systems to route it.  

 Yes, the aim of the mesh is decentralisation of the physical layer. Phones, home routers, etc would form dynamic multilateral connections to one another.

Good point about bitcoin and broadcast not needing routing. Indeed routing is probably the major challenge.

I fear with Starlink we are moving in the opposite direction… one ISP for everyone.
