LiFi or similar optical comms are also private, even stealth comms
   capabilities.
   I'm still sold on non-networked, radio wireless, stealth solutions.
   Even better ones without the need for any tech infrastructure. After a
   abandoning R&D, due to take-up of satellite comms, the DoD has returned
   to LF - UHF advanced radio (e.g., Mitre HF). NVIS (6-12 MHz) via
   wideband is a hot area.

     Cheap, works. Use whatever works.
     But for moving bandwidth, digging or stringing fiber and copper,
     or mounting laser... seems hard to beat on cost X speed basis.
     Maybe source simple IR laser module kit from China if it's still
     too high at retail due to fancy targeted-to-business-user
     remarketing bullshit.
     Generic RF kit, outside of WiFi std, probably isn't exactly
     cheap yet.
     Aren't [the rest of] free space optics solutions still big $$$? ...

     Not if it burns unaware people's eyes out.

     Is this UV / freespace tech at consumer production and price level,
     links?
     At Urban/Suburban environments densities distances,
     you probably want each node able to move at least 100Mbps
     over two simultaneous physical links to two other nodes for less
     than around $750 per node. 1 or 10 Gbps is trivial over fiber,
     and is easy to run to, or around, neighbors.
     Imagining entire buildings, neighborhoods... linking them up,
     serving as each other's transit... easily possible.
     Co-ops already do buildout models, but they're usually not
     per-node ownership, not mesh protocol'd, and not open to
     linking up, including due to contractual baloney that does
     not exist with true p2p.
     Taking that to fully distributed, open-neighbor to open-neighbor...
     from apartments, to farmland... that's the next level.
     Similar to cryptocurrencies... open p2p routing standards,
     and philosophy and responsibility of individual ownership,
     needed to prevent problems of centralization... are key.
     The independent nature sells itself under network effects.
