teleport Software Lets You Use One Mouse & Keyboard for Multiple Macs

"teleport is a simple utility to let you use one single mouse and keyboard to control several of your Macs. Works on Panther and Tiger. Simply reach the edge of your screen, and your mouse teleports to your other Mac! The pasteboard can be synchronized, and you can even drag & drop files between your Macs."

Wow, this is a great utility, basically a software-only KVM switch. The machines simply need to be on the same network. It has already proven to be a great boost to productivity, as I can set my laptop next to my main desktop monitor and interact with both from a single keyboard and mouse without any other hardware involved. This setup is great for authoring a website on one machine and then mousing over to the second to refresh / test it in a browser for example.
