Microsoft's free download of the day... Mouse without Borders.
Allows you to control up to four different Windows machines, running on different hardware, with a single mouse and keyboard... seamlessly across different monitors.
Also allows you to copy files by drag-and-drop across the different monitors. It supports multiple monitors on multiple workstations/servers.
I haven't tried it myself, but thought I would post it here for the adventurous minds. If anyone decides to give it a try, let us know how well it works!
