In the room have 20, computers connected together via LAN. Each computer has "Computer Name" and IP. On any computer (like a server), shared folders full for the remaining computers.
There is a certain tool (used on the server) to inform discovered another computer to access your computer and find out notification balloon in the lower right corner of the screen (like the Yahoo bubble meassge)
It is possible to write a computer log see what the other has operations on the shared folder. For example, copy one file where to go, or add a file. Like the log of TeamViewer software.
