In contrast to widely used commercial equivalent software, iTALC is free! This means you do not have to pay for expensive licenses or things like that. Furthermore the source-code is freely available and you're free in changing the software to fit your needs as long as you respect the terms of iTALC's license (GPL). Freedom in two ways!
iTALC has been designed for usage in school. Therefore it offers a lot of possibilities to teachers, such as
*see what's going on in computer-labs by using overview mode and make snapshots
*remote control computers to support and help other people
*show a demo (either in fullscreen or in a window) - the teacher's screen is shown on all student's computers in realtime
*lock workstations for moving undivided attention to teacher
*send text messages to students
*powering on/off and rebooting computers per remote
*remote logon and logoff and remote execution of arbitrary commands/scripts
*home schooling - iTALC's network-technology is not restricted to a subnet and therefore students at home can join lessons via VPN-connections just by installing iTALC client
Furthermore iTALC is optimized for usage on multi-core systems (by making heavy use of threads). No matter how many cores you have, iTALC can make use of all of them.
