[ale] Slightly OT: PI/Raspian Mesh Network Strategy?

[neal at mnopltd.com]

So considering the following Physical layout:

Business Comcast
       |
regular untinted Window in Building we can get Cat6 to
       |
100 feet of parking lot
       |
Storage Building with power and overhang to protect from rain
       |
150 feet of grass/trees - could run Cat6 wire easily
       |
Tent selling German beer with credit card readers needing Wifi (do I 
have your attention now?)

And assuming we'd like for people to be able to buy beer, and we have a 
modest budget for networking, are there reasonable mesh networking 
products that would work?

I have never put in a mesh network; if you read the fine print, they 
seem to assume all the nodes are clustered around a central node, not 
strung out in a line.   (i.e. no backhaul)

I was initially advised to research ESP32 boards, but the paint doesn't 
seem quite dry on those.  More of a Proof-of-Concept than a real 
internet sharing strategy.

OTOH, efforts to do that with Raspberry PI does seem like a real thing, 
eg

https://github.com/binnes/WiFiMeshRaspberryPi/blob/master/README.md

Which is extra handy for us, since we put up about a dozen PI units a 
people's homes for the Virtual Studio music thing, and aren't using them 
as much now.

Has anyone does this and have results to report?
