You might remember. We were talking about global connectivity for
everybody on this dirtball, then, suddenly, about affordable broadband,
again for everybody, then, suddenly, about fiber, for everybody, then
about a lot of other things, mostly unrelated.
Global connectivity for everybody (most values of everybody, at least) is
doable, fiber up every tree is of course another matter entirely. But, who
needs fiber up the wazoo, right now? I would take it, if I can have it, of
course, but I'd be pretty happy with anything above ~128/384 --
availability and flat rate would be much preferable to speedy, but cranky

Sure, that's the system you installed, and which works right now. LoS
photonics, swarms of mass-produced and mass-deployed low-LEO microsats,
active beamforming, digital pulse radio, Ethernet to the home, they're all
different technologies, with different capabilities and different

Wireless is a huge area, most of it is yet uncharted. LoS photonics and
digital pulse radio is wireless, and software radio routers are wireless,
too. I'm not aware of any company having competencies in all of these
areas, especially the lunatic fringe technologies like digital pulse

Iridium is too expensive, of course. It deserved to crash and burn, but if
the feds were willing to bail it out for their needs, why not. Your taxes
at work, and all.

So, what if the end user devices themselves route packets? Connectivity
doesn't always require voice, SMS or a speech recognition system can send
a small text message, which doesn't have to have high QoS. High-QoS 10
kBps might be the limit for streaming audio, but streaming audio is a
niche, albeit a currently very widely used niche.

Have you heard about 802.11b and successor technologies grassroute
networks, based on Mobile Mesh, etc? About communities doing their private
Ethernet to the home projects?
At least 802.11b based networks are very affordable, even given early
status of hardware development (I don't see why a mature 802.11b derived
router couldn't be sold for ~300-$400 in quantities, with zero operaton
costs but for the juice).
