USB switch for sharing one keyboard/mouse with two machines

You could just get a cheap usb kvm off of eBay. I picked one up but I don't really use it for the video switch anymore. I did use it for the usb switch though. The only problem was that it was ps/2 keyboard, ps/2 mouse and then usb. The device got its power from the ps/2 keyboard input and both ps/2 keyboard inputs needed to have power. Obviously my mini doesn't have a ps/2 output so I simply plugged the second ps/2 keyboard cable into the ps/2 mouse slot on my pc. Hey presto, it works! The pc doesn't actually have to be on, it just has to be plugged into the mains.
There are probably other solutions that don't require this powering. If there aren't and you don't have any ps/2 outputs then I'm sure it wouldn't be too hard to jerry rig the ps/2 connector's power lines to a small dc adaptor.

Use SYNERGY or TELEPORT. Both allow you to share mouse/keyboard across multiple computers; all without the clutter of KVM switches or extra hardware.
Good luck.
