There are places where you might want to hand-configure
IP addresses too, but DHCP is a lot handier.

How is that a solution? Proxies are used where you don't
allow direct outbound access. How do you do ftp without
configuring a proxy on every client?

How do you propose this should work without per-box configuration?

OK - ftp breaks when you NAT it too - sometimes.

Yes, just mirror the whole internet locally - or at least
all yummable repositories...

And all of the fedora repositories, and all the 3rd party
add on repositories, and the k12ltsp variations, and the
ubuntu/debian apt repositories.

It doesn't make sense to cache things unless at least one
person uses it. The point of the internet is that you can
get the latest when you need it, and the point of a cache
is that only one person has to wait.
