Maybe only a handfull of you will find this useful but for me it’s been a great find. Synergy allows the easy sharing between PC’s, Macs and Linux’s with one set as the server IP and the rest clients. It works exactly like a multimonitor setup and is nearly seemless and instant. $19.
It’s cool, we use it at work for Simulation Instructor stations…
I used to use this at two of my previous jobs. It’s a useful piece of software that basically lets you share a keyboard and mouse between PC’s sitting next to each other.
