Long time ventoy user, here. I absolutely love this software, there's always a usb stick with ventoy and a bunch of useful isos in my pocket.
The really intriguing feature is the ability to run vDisk files (as long as there's a linux distro within it) thanks to the VtoyBoot plugin[1]. I'm actually trying to build my own customized arch version with all my software (and potentially keys) installed so I can get rid of having to bring around any hardware. The only problem I'm facing is that it seems that ventoy boot does not work very well with luks containers.
