iTALC is a use- and powerful didactical tool for teachers. It lets you
view and control other computers in your network in several ways. It
supports Linux and Windows 2000/XP/Vista and it even can be used
transparently in mixed environments!

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.
