Synergy2 - Multiple computers, one set of input devices

I've run across far too many people who have two sets of keyboard/mice that they use on a regular bases. There is a solution to this, and it's called Synergy.

Just download it, install it on a couple computers, and you can share a single keyboard/mouse across them. They don't even have to be the same platform, I'm right now typing on my OSX laptop through a keyboard plugged into my desktop PC. It works over any IP network. If you have the monitors next to each other you can even mouse between them just like a dual headed display. If you have to switch monitors to view different computers, you can set up a hotkey to do switch your input target.

(This is not a monitor sharing / KVM solution)

Only problem is it ain't encrypted, so be careful if your on a public network. There's ways to pipe it through an SSH tunnel if that's an issue for you.
