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.
