iTALC

iTALC is a useful 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 XP, Vista and 7 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, and lock workstations for moving undivided attention to teacher.
