[Running a single computer]

I want to run a WO show using a single computer and 1 license key. I will be outputting to 4 seperate projectors to create a blended show. Is this possible? Can i produce this show on the same computer or do I need to use a seperate production computer?

[Running Watchout without a production computer]

Is it possible to run a WO show without a production computer... using 1 display computer and 1 license? Do I need to push the files from my production computer, first, to this display computer or can I just transfer the files over using conventional means, like a thumb drive?

[Upgrade question]

Is version 5 backward compatible? I have some old shows in a few museums that are still running version 2.3. Will I be able to play them using the version 5 license?
