Hi,

I am looking to have 3 computers share a single monitor. Requirements as follows:

1. Only one computer output needs displayed at any given time.
2. All computers are on....even if not displayed.
3. Able to switch display of computers easily, without having to reboot any of the machines or climbing under the table.
4. If monitor has built-in speakers...they would also be shared.

Also looking for a way for all 3 computers to share a single keyboard/mouse.

Basically, I need all three machines to do different things, but need to cut down on the desk space they take up. Plenty of room on the floor for the towers...but desk too cluttered.

Do these devices exist? Recommendations?
