20 XO-1s is the typical starter school we set up in Haiti, many
simultaneously trying to access Internet-in-a-Box with XSCE, almost but not
quite succeeding :-)
The challenge is that several schools (hope) to expand their XO count
dramatically this coming year. Of course server strength,
networking/electrical infra is across the map given Haiti's schools are
almost all unique creatures w/o govt support. Depending on a couple hours
of electricity per day, broken inverters/solar/charge controlers/batteries,
legacy wiring, cement/tin physical architecture, voodoo finances/donations
on a good day, etc.
One Haiti school began with 100 XO-1.75s but currently only ~50 are
operating, not quite ready for IIAB/XSCE until we have stronger guarantees
this will run reliably across a larger number of XOs.
Hence the "universal request" for a $200-300 IIAB server+Wifi that will
serve a small school or large classroom. Luckily we don't have 100-150
kids in Haiti classrooms! As some very unfortunate countries attempt.
I very rarely see more than 30-40 kids in a Haiti classroom -- that would
be a really great scalability target for this year if we're so lucky
(first+foremost understanding which IIAB usage patterns damage others'
throughput to better warn our kids!)
