First, the snippet provided is a contrived example of a much larger program.

(written in python3 with access to 3.4 if necessary)
The goal: To connect to a listening socket and send commands to the cmd.Cmd()
loop running, then show the output to both stdout and the remote connection.
Right now, I have a solution that will work as long as everything that needs to
get sent to stdout and the socket is return'd from each function instead of
printed.
Because this is already a larger project, I would prefer not to have to go back
through and refactor everything to facilitate the remote control (the actual
program involves threading and locks etc etc).
I feel like there should be a fairly simple solution dealing with duplicating
the file descriptor or something similar. I've messed around trying to find
something like that, but without success.
I've also looked into the contextlib.redirect_stdout, but it expects a file
type object. Also, using socket.makefile() results in the returned object not
having a fileno() method, so I can't use select on it.
Basically, I'm hoping someone here knows some file descriptor-fu or some other
cleaner solution.
Any help would be appreciated!

You could replace the current sys.stdout object with your own object
that copies to the original sys.stdout object and the socket.
