Could it be possible to install XNSW on machines connected to remote (distributed around a venue/building) displays which could be set as slaves.
Having one machine on the network set as the master.
Whatever setting I make on the master are reflected on the slave displays. Whether it's countdown or stopwatch, or even just TOD.
This is inspired by an event that I'm working on right now.
I was going to use an application that sends out keystrokes over the network, but I need to be able to change what XNSW is doing throughout the day, so doing this on all machines is becoming a pain.
