Folks are increasingly aware of screen sharing apps like VNC, but what about solutions that allow you to control multiple computers with a single keyboard and mouse?
Back in the day, there was an interesting MacOS 7 hack that would send mouse and keyboard input from one computer to another (after some very easy configuration), today, in the days of OS X, I can find two solutions:
Teleport works most like the old Classic Mac OS hack I remember, in that you need only mouse to one side of your screen to switch focus to another Mac. Mousing back brings focus and control back to your ‘home’ Mac. KMremoteControl goes cross platform with Windows PCs, but it isn’t as slick as Teleport (nor is it free).
I did find one annoying bug in Teleport, however. With my setup, it seems that I have to confirm the configuration prior to mousing over to the remote system. I’d like to be able to configure a remote control connection and use it without repeatedly having to confirm it in the preferences pane, but the app shows a lot of promise. The developer, who had left it as a public preview for some time, seems to be returning to it “because I’ll use it for my mac mini….”
Sort of related: Here’s a list of remote access solutions for Mac at Pure-Mac.com. The list doesn’t include Teleport or KMremoteControl and it’s probably missing others, but it may still be useful.
