I have been developing this tool for about 2 months, and it is currently being used in my office successfully.
If you have lots of computers in your network, primarily on windows network, then this tool can save you some work. You can put all the IP addresses/machine names in the list and share it across the network so that everyone can access it. All you need to do is to start the application, direct it to the location of file, restart it and its ready to use.
You can use three tools - RDC (if your OS has it installed), VNC viewers (need to be configured), and Netmeeting (if it is installed on you machine). It will not save passwords for now, because of some limitations of the tools used.
Give it a try. I will be happy to assist you in case you are unable to make out what it is.
