That is overkill for what I'm talking about.

I'm talking about the ability to distribute a single connection (possibly a 
consumer dishy, possibly a surviving landline) to a tent city of a few hundred 
(under a thousand) people. Provide some caching of the service, but also provide 
local communications (email, chat, etc)

The Red Cross and others are setup to provide food and shelter, but local 
communications, announcements, etc (including games and other things to keep 
kids out of trouble) seems like the sort of thing that we should be able to 
setup on the cheap.

you are again mixing services. The direct-to-phone cell service is 7Mb for a 70 
mile cell.

I don't know the dishy cell size, but I think it's substantially smaller than 70 
miles

We have seen community service happen in some places, early on SpaceX showed 
some remote Indian villages getting a single dish for the community

too many people (including too many techies) think that providing wifi service 
out from a point is so trivial that anyone can do it.

yep
