They need the money to buy heavy duty test score erasers.  :-)

I get 12M at home. I can't figure out why a school can't come up with
$100/mo and a cable line. 

Oh. school. $$

I don't have any in my service area that don't have a proxy. Before the
majority of mine all had fiber between the bulk of their schools-
there's a couple that have wireless links because of multiple carriers
and that mess, and a few that have no choice but phone-line based
solutions-  I had a few that used dual-level proxies, too. Since they
had, say, 768k/sec back to the board office, we put proxies in local to
save both internal and external slowness. This was when a district would
have 1 T1 line.

Of course, back then, squid was VERY scary to configure. Not so much
anymore. I suspect some of the boxes they've paid for are indeed squid.

The last time I saw some stats, schools average about 40% cache hits. It
helps, of course, but 3megs is still not that much for a whole school.
