Aten is a company I've checked out before, not surprisingly, both times it was a KVM switch. If you don't know already, that's because that is all Aten does. KVM's, are used to control 2 or more computers from a single set of "Keyboard, Video and Mouse". Almost every computer repair shop and server farm admin uses or wants to use a KVM. It keeps the costs down, and just make things easier to deal with. Server farms can have hundreds of computers controlled by half a dozen KVM switches that takes up only a single "U" worth of space. If you've ever seen '24' you've seen them go to the giant server room and pull out a sled that has a LCD monitor and keyboard built in, that is a KVM unit.
