iTALC (intelligently Teaching And Learning with Computer) is open source software used for managing classroom computers in Linux and Windows. iTALC enables teachers to remotely monitor and control students’ computers. This allows the teacher to perform demonstrations, to close windows and to shut down the computer. The program was developed as a free alternative to MasterEye.

Originally, iTALC was available only for Linux. In the middle of 2006, in the course of the Qt4 porting, support for NT-based Windows versions was added. Additionally iTALC transparently handles mixed computing environments, e.g., a linux based teacher’s computer can access pupils’ Windows computers and vice versa.
Features of iTALC include the following

Overview mode (allow previewing screens for each pupil computers in a small preview window)
Previewing computers in predefined classroom segment
Demonstration mode (either in a frame or window) – which the teacher’s screen is broadcast to all of the pupil’s computers in real-time
Barriers of the pupil computers, in order to direct attention on other things
Send text messages to students
On and switching individual or all computers off over network (Wake on LAN)
Snapshots for evidence protection, e.g. during infringement of any user rules
iTALC is developed in Trolltech Qt/C++ and is therefore compatible with both 32-bit Windows and GNU/Linux systems. iTALC in its version 1 was not designed to work with Windows Vista or Windows 7, however this problem was fixed in 2011 with releasing version 1.9.6 of iTALC (earlier, the developer has unofficially stated that a 2.0 release compatible with current and future releases of Windows will be made is Q3/Q4 2011

UltraVNC
UltraVNC allows the use of a remote computer as if the user were in front of it. This is achieved by sending mouse movements and key-presses to the remote computer, and replicating the remote computer’s display (subject to differences in resolution) locally in real time. UltraVNC bears a strong resemblance to RealVNC Free Edition. However, in addition to remote control it adds various features, such as an encryption plugin to secure the client/server connection. It also supports file transfers, chat functionality and various authentication methods. The two computers must be able to communicate across a network, such as a local subnet, internal network, or the Internet. The software is free and distributed under the terms of the GNU General Public License.

It can use an optional mirror driver, to be installed on the remotely controlled computer, for fast and efficient notification of screen changes with very low CPU load
