Somebody might care to contact ANTEL in Uruguay.  They invested 
humongous sums in this sort of thing, sums that later were questioned :-)

In the 1997 they hooked up to big fanfare every single one-room school 
in the country with some sort of wall-mounted hardware that apparently 
was cell-phone related.

With an Aussie donated 14.000 external modem, Escuela 19 de Arequita 
connected to international educational projects at 2400 bps, including 
having the names of the Arequitense kids sent in the CD that went with 
the NASA Mars probe.  The one that crashed in Mars...  The next year the 
school closed, went under 6 kids :-(
