During the adaptation of SL for russian school education we had the same
problem -- providing of porno or terrorist-oriented materials for child is
a crime in Russia.

Our solution -- a lot of packages for setting and managing firewall
protected internal network and infrastructure settings for auto-detect
proxy (SQUID) included to our specialized school distro -- NauLinux. SQUID
connect to schools LDAP users/group DB with a different access polices for
different user groups (teachers and pupils, for ex.). White list managed
by some web-interfaces: more simple -- just for uploading list of
educational resources placed in text file, and advanced interface for full
accepting/rejecting control.
