Wouldn't this be better in tech-kern?

Why do you need a kernel solution? Can't you make a SUID 0 process
which checks uid is dustin, opens the socket, does setuid(getuid())
etc and execs dustins process either with the open socket on a well known
file descriptor or passing the number of the file descriptor as an argument?
