I have two PCs on my desk at work, each with its own dedicated mouse, keyboard, and monitor. I prefer having the extra dedicated monitor dumping 'tail -f /var/log/maillog' fullscreen from our primary mailserver, and with browser windows open for Nagios and MRTG 24/7.
I'm not running a KVM for any other extra machines, and I'm not doing multiple displays on any of the PCs. I also have my own laptop which I bring into work on occassion (when I want a portable SSH terminal or need a serial port to do work in any of the wiring closets). What this does is allow me to pick any of the three mouse/keyboard sets at my desk, and control all of the computers at once. It can even copy and paste out of a doc on one computer over to another, and drag and drop files between them -- no mapping drives or writing SMB \\HOST\C$ type notation in Explorer. I can even CTL+ALT+DEL to login into every computer simultaneously, or lock them all together when I leave for lunch.
Very elegant, and very simple to setup. There is a third party app which does this already named Synergy, but the UI sucks and it's buggy as heck. This is a simple MS developed PowerToy.
Now I know why Great Plains/Dynamics is a P.O.S. Because the guy on the team that actually knows his ass from a hole in the ground has been tinkering with this nifty little PowerToy.
This utility does not allow you to span monitors with a single app, like a hardware based multi-display would. It just 'lets you drive' up to four PCs with any mouse/keyboard pair connected to any one of the PCs. Each still needs its own monitor.
As someone that has inadvertantly grabbed the wrong keyboard off my desk and rebooted a router or a firewall by accident, this will save me a lot of grief. I can hide my other keyboards from myself. :tongue2:
