AF Reserves.  I'm busy during the work day and can't get on the phone
during Bascom's tech support hours (they close at 3PM our time).  I
should have explained that better.  :-)

Yeah, it is.

Yup.  Of course, that doesn't actually tell us what it does so much.

I think I'll contact the teachers and find out if they even know the
software is there.  If not, it's gone...

I haven't had any experience with IPCop, so will probably utilize a nice
Slackware install with my iptables script and squid/squidguard or
DansGuardian to filter stuff out.  Either that or I'll talk them in to
spending $50 on a cheapo DSL router.

A gig of RAM alone will run you close to $200.  The cheapest CPUs Fry's
have are all over $50.  $10 for a HSF.  $30 for a case (online, Fry's
doesn't have cheap cases), etc, etc... I'm currently building fairly
barebones systems for about $350 in hardware.  Unfortunately I also must
pay the Microsoft tax on these systems.  :-(

I wonder how best to implement something like that with multiple
servers.  I should play around with it a bit...

Exactly; they're great terminals.  They're not good for much else,
though.  :-)

I'm surprised we haven't had a ton of disk failures, as well.  Happily
surprised.  Most of the systems were expensive workstations in their
day, though.
