“This document describes how to set up iTALC on Ubuntu 7.10.
iTALC is an open-source classroom management solution that lets you
view and control other computers in your network. It lets you
remote-control other computers, show the teacher’s screen on all
students’ computers, lock workstations, send text-messages to
students, power on/off and reboot remote computers, etc.
“Taken from the manual: ‘iTALC is a didactic software program,
which was developed especially for computerwork at schools…'”
