I want to send someone an offline app (but would be streamed online by other app like OBS) to use, while wanting to show him that his PC won't be infected (or similar) by that app.
App will rely on some external libraries (seemingly all from trusted sources) and will use mic and camera.
How to approach this so that receiver of app shouldn't worry too much.
I searched and found Docker is pretty secure, but the performance of app is important (especially considering streaming).
