For anyone curious there is a somewhat similar thing in Linux called Abstract Domain Sockets. These are Unix domain sockets where the first character is NUL ('\0')

I am working on a game where every player has system resources on a Linux computer. The basic idea is that some resources need to be shared or protected in some ways, such as files, but the core communication of the game client itself needs to be preserved without getting in the way of the real system environment.

I am using these abstract data sockets because they sidestep most other permissions in Linux. If you have the magic numbers to find the socket, you get access.
