I have an unusual situation. I have two computers in my office connected to a KVN switch. I have 12 computers upstairs connected by a KVN switch. I would like to be able to control the computers upstairs from my office - copy files in both directions and control programs on the other computers.
I tried Synchronicity but I couldn't get it to work. It would switch the mouse but not the screen. They couldn't help me and refunded my money.
I got a free trial of Multiplicity, but due to the hurricane and other issues I didn't get to try it during the trial period. Will Multiplicity work for what I want? It controls only up to 9 computers, so could I have two copies of it running on one computer in my office? (Or, if not, one copy on each of my computers downstairs, each controlling some of the computers upstairs.)
