I am using to computers for my display this year. The main home computer upstairs in the warmth of my lounge room for the programming and general duties of getting ready for this years display. Down stairs in my workshop I have another computer that I am going to use to run the display, ( I don't have a pi, nor do I want to get one at this point). I use the down stairs computer to do the testing and fixing, I can set the lights up down there and not invade my upstairs space with all things blinky like I have in past years. this presents a problem in that when I make changes on one computer I have to transfer data between the two machines, I have a few ways to do this, via the network, USB, dropbox (which I don't know how to use), but it all seems a tad clunky, and easy for me to screw up.... which I think I have. Both computers are on the network and I can save from the downstairs computer to the main computer upstairs, although interestingly cant do the other way, nor does the upstairs computer let me test the lights.... Anyway, what I would like to do, is have xlights data on just one computer and have both computers read and write to that one data file. I know its possible, I just don't know how to do it, or set it up. Is there someone who understands what I am after, and can help me achieve this?
