I have been using Synergy for about a year and I really like it. It passes the clipboard along with keyboard and mouse commands to a second pc over the network. I’m using it with two dual display systems. Besides the fact that you can’t drag windows from one pc to another, it really feels like I am working on a single system with four monitors and two cpu’s. It let’s me spread processing around and maintain two versions of the same browser mounted shared drives let me share hard drive space. Anybody that has two computers near each other or a laptop and pc should check it out.
