RealVNC is a handy open source tool that allows people with a wide variety of different kinds of computer to view and control the screen and keyboard of a machine from across the Internet. It does the same kind of job as PC Anywhere but it costs nothing and it is small and very easy to install. Windows XP Professional can do this too but RealVNC works on anything from Windows 95 upward and 39 other operating systems!
I found it very useful when I wanted to help my Dad 3000 miles away sort out computer problems. Thank you AT & T Research and the University of Cambridge!
