This definitely sounds like it fits. I've never mucked about with TCP before but I don't think there's anything in my way conceptually, at least.

I've just scrapped around with this in Go - I'm sure you can convert to Rust with ease - using cowsay as the target command line app:

package main

import (
    "fmt"
    "net"
    "os"
    "os/exec"
)

func main() {
    listen, err := net.Listen("tcp", "127.0.0.1:6000")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    conn, err := listen.Accept()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    cmd := exec.Command("cowsay")
    cmd.Stdin = conn
    cmd.Stdout = conn
    cmd.Start()
    cmd.Wait()
}

Above and beyond, David, thanks for the sample!

That might be exactly the ticket - no real need to translate to Rust, I might just start with your Go template if you don't mind, that looks like less friction.
