Outside of lots of non-obvious problems with synchronization, this is your example that best fits the idea. This interface is probably a good one.
> And of course you can get a peer address from /dev/tcp
You will have lots and lots of problems with access controls if this is your only interface.
> Shared memory can be a file
Coercing random access memory into a serial file just to go and emulate a random access over that file is... not a great way to deal with a high-performance primitive.
