I'm curious about the license requirements. Is it 1 license per install, or 1 per install that is currently serving?

I have two devices, but I will never use them at the same time (and if I do by accident, I'd expect your software to stop working).

It's perpetual license. So you can enter the license key on a new device and it will automatically deactivate previous device.
