Hi, We started using this at work and got pretty amazed. http://synergy2.sourceforge.net/ In short: "Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It's intended for users with multiple computers on their desk since each system uses its own monitor(s)." So you can use your iBook and your windows machine at work (if applicable) and use only one mouse and one keyboard. Great open source tool :-) Cheers, Alex http://slashgeo.org
