I just found out about this free software from Microsoft for sharing computers with Windows XP. It is called the Microsoft Shared Computer Toolkit for Windows XP: http://www.microsoft.com/windowsxp/sharedaccess/default.mspx. It is particularly useful for places such as libraries or schools providing public access to computers, but I immediately thought of its application in another area. I am hoping that at least one person out there reading this post is involved in setting up shared computer labs for underprivileged countries and could benefit from using something like this.
