Will my licence work on two PC's at the same time?
If so, I could cheat the internal camera idea by running a second instance of the same file and use NDI to make the second display view available as a media source for the first machine to use.
That would allow live camera control too, which would be quite funky.
(In fact, thinking about it; then I could send the display of each machine to the other so the content would be available in both. It will be interesting to try that out and see if we can get some weird feedback things going on...)
